In covering distance, the speed of A & B are in the ratio of 3:4.A takes 30min more
than B to reach the destination. The time taken by A to reach the destination is.
5 hrs
3 hrs
2 hrs
4 hrs
Explanation:
Ratio of speed = 3:4
Ratio of time = 4:3
let A takes 4x hrs,B takes 3x hrs
then 4x-3x = 30/60 hr
x = ½ hr
Time taken by A to reach the destination is 4x = 4 * ½ = 2 hr
Ratio of speed = 3:4
Ratio of time = 4:3
let A takes 4x hrs,B takes 3x hrs
then 4x-3x = 30/60 hr
x = ½ hr
Time taken by A to reach the destination is 4x = 4 * ½ = 2 hr
