Question
In covering distance, the speeds of A & B are in the ratio of 3:4.A takes 30min more than B to reach the destination. Find time taken by A to reach the destination?
Answers
if a and b are the times, since the speeds are in ratio 3/4, the times are related by
a/b = 4/3
a = b+30
a = 120
b = 90
a/b = 4/3
a = b+30
a = 120
b = 90
