In covering a distance,the speeds of A & 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
A
2 hours
B
2.5 hours
C
1.5 hours
D
3 hours
Correct Option - A
Explaination
Speed and Time are inversely proportional.
Time taken by A and B will be the ratio 4:3.
Let the time taken by A and B be 4x hours and 3x hours.
4x-3x = 1/2
x = 1/2
4x=2 hours
