Correct answer is: 40 sec

Explanation:

Ram and Rahim standing at a distance of 680 m run towards each other at a speed of 8 m/sec and 9 m/sec respectively

Total speed at which they are approaching each other = 8 + 9 = 17 m/s

\(\text{Time taken }= \frac{\text{distance}}{\text{speed}} = \frac{680}{17} = 40 s .\)
