Question 1107988
A speedboat moves at a rate of 25 km/hr in still water.
 How long will it take someone to ride the boat 62 km downstream if the river’s current moves at a rate of 6 km/hr?
:
When a boat travels downstream, the current speed is added to still water speed:
6 + 25 = 31 km/h is the effective speed
:
Time = dist/speed
t = {{{62/31}}}
t = 2 hrs to travel downstream 62 km
