Let x be the speed of Aro’s paddling and let y be the speed of the river. Upstream: 1.04 = x – y

Downstream: 2.08 = x + y

Aro can paddle at a speed of
miles per hour.

The river’s speed is
miles per hour.

Aro can paddle at a speed of 1.56 miles per hour.

The river’s speed is 0.52 miles per hour.

Step-by-step explanation:

trust

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
