Question
A boat takes 2 hours to cover 60 km downstream. If the
speed of the stream is 3 km/h, then how far will it go upstream in 6 hours?Solution
ATQ,
Downstream speed of the boat = 60 ÷ 2 = 30 km/h Speed of stream = 3 km/h Speed of boat in still water = 30 - 3 = 27 km/h Upstream speed of the boat = 27 - 3 = 24 km/h Distance covered upstream in 6 hours = 24 × 6 = 144 km
