In a covering, a certain distance, the speeds of A and B are in the ratio of 3:4. A takes 30 minutes more than B
to reach the destination. The time taken by A to reach the destination is?
1 hour
1 1/2 hour
2 hour
2 1/2 hour
Explanation:
Ratio of speeds = 3:4
Ratio of times taken = 4:3
Suppose A takes 4x hrs and B takes 3x hrs to reach the destination.
Then, 4x - 3x = 30/60 $\Rightarrow$ x = 1/2
Time taken by A = 4x hrs = 4 $\times$ 1/2 = 2 hrs.
Ratio of speeds = 3:4
Ratio of times taken = 4:3
Suppose A takes 4x hrs and B takes 3x hrs to reach the destination.
Then, 4x - 3x = 30/60 $\Rightarrow$ x = 1/2
Time taken by A = 4x hrs = 4 $\times$ 1/2 = 2 hrs.
