Answer / abhilasha
Cap fell here
A-------------->B----------------->C Upstream-------->
1mile
-----5 min--------
A<-----<<-------B<--------<<------C <<------Downstream
---------------5 min---------------
cap reached
here
From B to A total time taken by cap to reach at A =5+5
=10 min (B-->C--C-->B-->A)
Total distance covered by capto reach frm B to A =1 mile (with speed of river)
so speed of river =1 mile/ 10 min
= 1/(10/60)hr
=6 mile/hr Ans

Answer / 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.

Answer / 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
