Problema Solution
A motor boat travels at the rate of 50 kph down the river. If the current of the river is 5 kph. How far can it travel up the river in 2 hours?
Answer provided by our tutors
trsaveling velocity of boat=50kmph
velocity of current=5kmph
velosity of boat in still water=50-5=45kmph
velocity of boat in opposit to current =45-5=40kmph
distance=velocity*time
=40*2
=80km
