Shubham runs at a speed of 8m/s. Vijay run behind him after 3 seconds at a speed of 14 m/s. After how much time Vijay will catch the thief?

OPtion

1) 2 seconds
2) 5 seconds
3) 7 seconds
4) 14 seconds
5) 8 seconds
6) 4 seconds
7) 3 seconds
8) 6 seconds
9) 8 seconds
10) None of the above

Solution

Relative speed between Shubham & Vijay = 14- 8
= 6m/s
Vijay lags behind Shubham by 3 seconds at start.
Hence time taken by Vijay to catch Shubham
= Distance covered by Shubham in 3 sec / Relative speed of Vijay
= 8m/s x 3 sec / 6m/s
= 4 seconds
