Question : In covering a certain distance, the speeds of A and B are in the ratio of 3:4. A takes 30 minutes longer than B to reach the destination. The time taken by A to reach the destination is:
Option 1: 1 hour
Option 2: 1$\frac{1}{2}$ hours
Option 3: 2 hours
Option 4: $2\frac{1}{2}$ hours
Correct Answer: 2 hours
Solution : Speed is inversely proportional to time. So, $s_1:s_2 = t_2: t_1$ $s_1:s_2$ = 3: 4 $t_1: t_2 =$ 4: 3 Let $t_1= 4k$ and $t_2 = 3k$ ATQ, $4k-3k = 30$ minutes $k =30$ Time taken by A to reach the destination = $4k
