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?  Choose the correct choice:
A) 1 hrs
B) 8 hrs
C) 2 hrs
D) 6 hrs
E) 9 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 =&gt; x = 1/2   Time taken by A = 4x hrs = 4 * 1/2=
