Question

Mary goes walking every day. She walks 14 ft. every 4 seconds. Which equation models the relationship between the time Mary walks, x, and the distance she walks, y?

Answer 1

y=3.5x

Explanation:

to find the the feet mary walks per second, divide 14 by 4

14/4=3.5 feet/second

the total distance mary walks can be represented by multiplying the number of feet she walks per second by the number of seconds she walks

y= 3.5x

in this model, x is seconds
