An african elephant can run 15 mph. Write an equation using two variables to show the relationship between the how many hours the elephant run, r, and the distance the elephant ran, d.

Answer 1

The equation that represents the relationship between the number of hours the elephant runs, r, and the distance it ran, d, can be expressed as:

d = 15r

In this equation, '15' represents the speed of the elephant in miles per hour. Thus, multiplying the speed (15 mph) by the number of hours the elephant runs (r) gives the distance covered (d) by the elephant.
