hat at the point from where they began boating after 5 min.
Find out the speed of river.

Answer Posted / shiva ramnos

The hat fallen after travelling one mile and after that they
travelled for (5MIN.)
so that hat travelled down stream for one mile and they
collected the hat after 5mins of travel down stream. So the
total time they spent after losing hat is 10 minutes.In this
10 minutes the hat exactly traveled 1 mile(i.e with river
speed). So its very clear----> the river speed is 6miles/hour.
