Akash rows downstream 28 km and upstream 16 km taking 5 hrs each time What is the velocity of curren...........

Downstream velocity is the velocity of the boat & stream added together.
Upstream velocity is the velocity of the boat gets subtracted from the stream velocity.
Let v & s be the velocity of the boat & stream respectively.
(v+s) 5 =28…(1)
(v-s) 5 =16…(2)
10s = 12
s =12/10=1.2 km/hr
