Problem 10 : 

PQRS are four places. Distance from P and Q is 75 miles, distance from Q to R is 15 miles more than the distance from P to Q and the distance from R to S is four-third of the distance from Q to R. Find the total distance from place P to place S. 

Solution :

Distance from P to Q : 

= 75 miles

Distance from Q to R : 

= 75 + 15

=  90 miles

Distance from R to S : 

= 4/3 ⋅ (Distance from Q to R)

=  4/3 ⋅ 90 miles

=  4 ⋅ 30

=  120 miles

Total distance from P to S :

= (P to Q) + (Q to R) + (R to S)

= 75 + 90 + 120

= 285 miles
