Question

A family is canoeing downstream with the currents. Their speed relative to the banks of the river averages 2.75mi/h. During the return trip they paddle upstream against the currents averaging 1.5mi/h relative to the river bank.
Paddle ing speed + current=rate of canoe
Paddling speed -current = rate of canoe
Write an equation for the rate of the canoe downstream.
Write a rate of the canoe upstream.
Solve the system to find the family's paddling speed in water.
Find the speed of the current of the river.
