It is given that sonam run at a speed of 25 km/hr.

We need to find the time taken by sonam to cover 800m.

1000 m = 1 km

1 m = 0.001 km

800 m = 0.8 km

Speed = Distance/ Time

Time = Distance/ Speed

Substitute 0.8 for distance and 25 for speed.

Time = 0.82/25

0.032

Time taken by sonam to cover 800m is 0.032 hours.

1 hour = 60 minutes

0.032 hours = 1.92 minutes
