A river 1 km wide is flowing  at 3 km/h . A swimmer whose velocity in still water is 4 km/h can swim only for 15 minutes.In what direction should he strike out in order reach the other bank ? What is the total distance covered ?

Hello,
 
Suppose he starts from ‘O’ and reach the opposite end ‘A’ of the bank.

The distance travelled by the man is the width of the river, as he moves from O to A only.
 
Hope this helps,
Keep posting and have a great day!

You are wrong the resultant velocity will be 5 kmh and distance travelled will 1.25 Km. Go and see S.Chand Physics book. You are an Expert and your are wrong. Shame on you.
