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!
