Worksheet given in this section will be much useful for the students who would like to practice solving word problems using unit rate.

**Problem 1 :**

In a business, if A can earn $ 7500 in 2.5 years, find the unit rate of his earning per month.

**Problem 2 :**

If David can prepare 2 gallons of juice in 4 days, how many cups of juice can he prepare per day ?

**Problem 3 :**

If John can cover 360 miles in 3 hours, find the number of miles covered by John in 1 minute.

**Problem 4 : **

75 basketballs cost $1,143.75. Find the unit rate in price per basketball.

**Problem 5 :**

In 36.5 weeks, Miguel raised $2,372.50 for cancer research. How was his unit rate in price per week?

**Problem 6 : **

Shanel walks 2/5 of a mile every 1/7 hour. Express her speed as a unit rate in miles per hour.

**Problem 7 : **

Declan use 2/35 of a gallon of gas for every 4/5 of a mile that he drives. At this rate, how many miles can he drive on one gallon of gas?

**Problem 8 : **

A person can cover a distance of 84 miles in 4 gallons of fuel. If he has 2.5 gallons, how many miles can he cover ?

**Problem 9 : **

If a person drinks 8 cups of apple juice per month, how many gallons will he drink in one year?

**Problem 10 :**

My David earns $416 in 8 hours. How much does earn in 2.8 hours ?

**Problem 1 :**

In a business, if A can earn $ 7500 in 2.5 years, find the unit rate of his earning per month.

**Solution : **

**Given :** Earning in 2.5 years = $ 7500

1 year = 12 months

2.5 years = 2.5 x 12 = 30 months

Then, earning in 30 months = $ 7500

Therefore, earning in 1 month = 7500 / 30 = $250

Hence, the unit rate of his earning per month is $250.

**Problem 2 :**

If David can prepare 2 gallons of juice in 4 days, how many cups of juice can he prepare per day ?

**Solution : **

No of gallons of juice prepared in 4 days = 2 gallons

1 gallon = 16 cups

So, no. of cups of juice prepared in 4 days = 2 ⋅ 16 = 32 cups

Therefore, David can prepare 32 cups of juice in 4 days.

Then, no. of cups of juice prepared in 1 day = 32 / 4 = 8

Hence, David can prepare 8 cups of juice in 1 day.

**Problem 3 :**

If John can cover 360 miles in 3 hours, find the number of miles covered by John in 1 minute.

**Solution : **

No of miles covered in 3 hours = 360

Then, no. of miles covered in 1 hour = 360 / 3 = 180

1 hour = 60 minutes

So, no. of miles covered in 60 minutes = 180

Then, no. of miles covered 1 minute = 180 / 60 = 3

Hence, John can cover 3 miles in 1 minute.

**Problem 4 : **

75 basketballs cost $1,143.75. Find the unit rate in price per basketball.

**Solution :**

**Given :**75 basketballs cost $1,143.75

Then, price pf one basket ball = 1143.75 / 75 = 15.25

Hence, the unit rate in price per basket ball is $ 15.25.

**Problem 5 :**

In 36.5 weeks, Miguel raised $2,372.50 for cancer research. How was his unit rate in price per week?

**Solution :**

**Given :** Miguel raised $2, 372.50 in 36.5 weeks

Then, amount raised in one week = 2372.5 / 36.5 = 65

Hence, the unit rate in price per week was $65.

**Problem 6 : **

Shanel walks 2/5 of a mile every 1/7 hour. Express her speed as a unit rate in miles per hour.

**Solution : **

**Given :**Shanel walks 2/ 5 of a mile every 1/7 hour

We know the formula for speed.

That is, Speed = Distance / time

Speed = (2/5) / (1/7)

Speed = (2/5) ⋅ (7/1)

Speed = 14 / 5

Speed = 2.8 miles per hour

Hence, the speed of Shanel is 2.8 miles per hour.

**Problem 7 : **

Declan use 2/35 of a gallon of gas for every 4/5 of a mile that he drives. At this rate, how many miles can he drive on one gallon of gas?

**Solution : **

**Given : **In 2/35 of a gallon of gas, 4/5 of a mile is traveled

2/35 of a gallon of gas -----> 4/5 of a mile

1 gallon of gas -----> (4/5) ⋅ (35/2) miles

1 gallon of gas -----> 14 miles

Hence, Declan can drive 14 miles in 1 gallon of gas.

**Problem 8 : **

A person can cover a distance of 84 miles in 4 gallons of fuel. If he has 2.5 gallons, how many miles can he cover ?

**Solution : **

**Given :** 84 miles can be traveled in 4 gallons.

Then, no. of miles traveled in 1 gallon = 84/4 = 21

Therefore, no. of miles traveled in 2.5 gallons is

= 21 ⋅ 2.5

= 52.5

Hence, 52.5 miles traveled in 2.5 gallons of fuel.

**Problem 9 : **

If a person drinks 8 cups of apple juice per month, how many gallons will he drink in one year?

**Solution : **

**Given :**8 cups in one month

1 year = 12 months

So, no. of cups in 1 year = 8 ⋅ 12 = 96 cups

1 gallon = 16 cups

Therefore, no. of gallons in 1 year = 96/16 = 6

Hence, he will drink 6 gallons of apple juice in 1 year.

**Problem 10 :**

My David earns $416 in 8 hours. How much does earn in 2.8 hours ?

**Solution : **

**Given :** Earning in 8 hours = $ 416

Earning in 1 hour = $ 52

Earning in 2.8 hours = 52 ⋅ 2.8 = 145.6

Hence, Mr. David will earn $145.6 in 2.8 hours.
