A boat covers 24 km downstream in 3 hours. If speed of current is 2 km/h, find speed of boat in still water.

Topic: Speed, Time &amp; Distance
Subtopic: Boats and Streams

A6 km/h

B8 km/h

C10 km/h

D12 km/h

Explanation

Downstream speed = 24 / 3 = 8 km/h. Downstream speed = Boat speed + Current speed => 8 = Boat speed + 2 => Boat speed = 6 km/h.
