Question 8 • GA-8th Grade Mathematics

Garrett is creating a table to model the speed of a canoe in a river. He knows that the canoe travels at 4 mph in still water. What does x represent in Garrett’s table?Canoe SpeedDirection on riverSpeedWith current (downstream)4 + xAgainst current(upstream)4 – x

Answer
A
speed of current in river
B
speed of canoe upstream
C
time of trip
D
distance traveled

Explanation

The canoe moves at 4 mph in still water. When it travels downstream, the river current adds to its speed, giving 4 + x; upstream, the current reduces its speed, giving 4 − x. Therefore, x represents the speed of the river current, choice A.
