A boat can travel with a speed of 13 km/hr in still water. If the speed of the stream is 4 km/hr, find the time taken by the boat to go 68 km downstream.

Answers

Answered by TPS

speed of boat in still water = 13 km/h
speed of stream = 4 km/h

down stream speed of boat = 13+4 = 17 km/h
distance = 68 km
time = distance/speed = 68/17 = 4 hours

So it will take 4 hours.
