Question

A rock climber's height, in feet, when climbing a shear wall can be expressed by the equation h=15t, where t is time measured in hours. Which best describes the proportional relationship?

Answer 1

The climber moves 15 feet per hour.

Explanation:

A rock climber's height, in feet, when climbing a shear wall can be expressed by the equation h=15t, where t is time measured in hours

h is distance and t is time.

`(h)/(t)=15`

or

`(d)/(t)=15`

Distance per unit time is equal to the velocity of an object.

velocity = 15 feet per socond

Hence, the climber moves 15 feet per hour.
