Question

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?

y = 420x

y = 470 + 50x

y = 50 − 470x

y = 50 + 470x

y = 470 − 50x

Answer 1

the last one

y = 470 - 50x

Answer 2

`y= 470 - 50x`

Explanation:

Wayne needs to drive 470 miles to reach Milwaukee. Suppose he drives at a constant speed of 50 miles per hour.

Let x represents the number of hours he drives and y represents the distance in miles.

constant speed is 50 miles per hour.

Distance =speed x time

speed is 50 miles per hour and time is x

So distance =
`50x`

Wayne needs to drive 470 miles to reach Milwaukee.

To find out y, we need to subtract 50x from 470

`y= 470 - 50x`
