CTS Company Numerical Ability Boats and Streams

In a river flowing at a speed of 4kmph, a speed boat goes 12km upstream and back to the starting point in 50 minutes. Find the speed of the speed boat in still water.

Read Solution (Total 2)

speed of boat= vkm/h
(12/v+4)+(12/v-4)=5/6

upstream+downstream=(12+12)/(50/60)
(sb+4)+(sb-4)=(1440/50)
2sb=28.8
speed of boat=14.4kmph.
