Question
The speed of a boat in downstream
and upstream is 30 km/hr and 22 km/hr, respectively. Find the approximate time taken by the boat to cover a distance of 160 km in still water.Solution
ATQ,
Downstream speed = 30 km/hr,
Upstream speed = 20 km/hr. Speed in still water = (30+20)/2 = 25 km/hr Time = Distance/speed = 160/25 = 6.4 hrs or 6 hours 24 minutes.
