Answer:
vₓ = 5.5 mile / h and = 2.5 mile/h
Explanation:
This is a problem of adding vectors, but since the canoe and the river are in the same direction, we can make an ordinary sum, write the equations for each situation
I rowed down the river. In this case the speed of the canoe and the river are in the same direction, consequently, they add up
(vₓ + ) = d / 1.5
I rowed up. In this case the canoe and the river have reversed directions
(vₓ- ) = d / 4
Feel us two equations with two unknowns,
Let's start by adding the equations
2vₓ = d / 1.5 + d / 4
2vₓ = 12 (4 + 1.5) / 4 1.5
vₓ = 11/2
vₓ = 5.5 mile / h
Let's substitute in the first of the two equations to find the speed of the river
(vₓ +) = d / 1.5
= d / 1.5 - vr
= 12 / 1.5 -5.5
= 8-5.5
= 2.5 mile / h
