A son and father goes for boating in river upstream . After
rowing for 1 mile son notices the hat of his father falling
in the river. After 5 min. he tells his father that his hat
has fallen. So they turn around and are able to pick the
hat at the point from where they began boating after 5 min.
Find out the speed of river.

Answer Posted / raviteja900

The hat fallen after travelling one mile and after that they
travelled for 5mins.
so that hat travelled down stream for one mile and they
collected the hat after 5mins of travel down stream

so the speed of river is equal to the hat speed but not the
boat speed as they row the boat even in down stream and
speed will be more than the river speed.

so the speed of river is 12 miles/hr
