Q.

In a race, the speeds of $A$ and $B$ are in the ratio $3:4$. $A$ takes 30 minutes more than $B$ to reach the destination. The time taken by $A$ to reach the destination is:

 A.

1 hr

 B.

 D.

2.5 hr

 Hide Ans

Solution:
Option(C) is correct

Ratio of speeds = $3:4$
Distance remaining constant, the ratio of time taken = $4:3$

$A$ takes 0.5 hours more than $B$

Hence time taken by $A=4\times 0.5=$ 2 hour
