Question

Manuel is biking at a constant rate.

The graph shows the ratio time : distance.
How long did it take Manuel to bike 4
miles?

Answer 1

30 min. The slope of the equation is 4/5 so if you follow the line you get (30,4)

Answer 2

30 minutes

Explanation:

Since it took him 15 minutes to bike 2 miles, we can say that he biked 1 mile in 7.5 minutes.

Since we want to know how long it took him to bike 4, let's multiply 7.5 by 4

7.5*4=30

So it took him 30 minutes to go 4 miles
