= 24 + 8
= 32
So, Joey's team danced for a total of 32 hours.
10. Answer :
From 2:15 P.M. to 4:15 P.M. is 2 hours.
From 4:15 P.M. to 4:45 P.M. is another half hour.
Then, the total time is
= 2 hours + 0.5 hours
= 2.5 hours
= 2 hours 30 minutes
So, the drive took him for 2 hours 30 minutes.
11. Answer :
Distance from place A to place B :
= 50 miles
Distance from place B to place C :
= 2 ⋅ (Distance from A to B)
= 2 ⋅ 50 miles
= 100 miles
Distance from place C to place D :
= 3/4 ⋅ (Distance from C to D)
= 3/4 ⋅ 100 miles
= 3 ⋅ 25
= 75 miles
Total distance (A to D) :
= (A to B) + (B to C) + (C to D)
= 50 + 100 + 75
= 225 miles
So, the distance from Place A to place D is 225 miles.
12. Answer :
