Thespeed of the river in \(km/hr\). Q. A boat having a speed of 5 km/hr. in still water, crosses a river of width 1 km along the shortest possible path in 15 minutes.
Walktwo to three minutes to pre-warm your body. Run 10 minutes at a comfortable pace to warm up. Repeat the following workout three times: Run one minute at a very challenging pace followed by one minute of walking. Run two minutes at a very challenging pace followed by one minute of walking and one minute of jogging.
Weare given that two thirds of the 6 km was covered at 4 km / hr i.e. 4 km distance was covered at 4 km / hr. Time taken to cover 4 km = 4 km / 4 km / hr = 1 hr = 60 minutes. Time left = 84 – 60 = 24 minutes. Now, the man has to cover remaining 2 km in 24 minutes or 24 / 60 = 0.4 hours. Speed required for remaining 2 km = 2 km / 0.4 hr = 5
