Wayne needs to drive 470 miles to reach Milwaukee. Suppose he drives at a constant speed of 50 miles per hour. Which function represents Wayne’s distance in miles from Milwaukee in terms of the number of hours he drives?


A.y = 420x

B.y = 470 + 50x

C.y = 50 − 470x

D.y = 50 + 470x

E.y = 470 − 50x
