Question

A boat running upstream takes 8 hours 48 minutes to cover a certain distance, while it takes 4 hours to cover the same distance running downstream. what is the ratio between the speed of the boat and speed of the water current respectively? 2 : 1 3 : 2 8 : 3 cant be determined

Answer 1

speed of boat =x
speed of current = y
distance = d
x-y=5d /44 ( d / time)
x+y= d/4
from both equations
x/y =8/3
so ratio can be 8:3
