Question

The speed of a roller coaster depends on the height it drops from. Which expression represents the speed of a roller coaster if it drops from a height of 200 feet?

A.speed(200)
B.200(speed)
C.200-speed
D.speed-200

Answer 1

The correct answer is Choice A.

If the speed is a function of the height, we would use the notation speed(height). On the left, we put the output and in the parenthesis we put the input.

We can change the word height to 200, because we know the height is 200.
