Answer:
It takes 2.4 hours to travel 480 miles.
Step-by-step explanation:
From the graph race car is moving at 100 miles in 0.5 hours. So, in 1 hour, car could travel 2*100 =200 miles per hour.
So, we can set up equation as
y= 200x.
Plug in y as 480 then solve for x.
480 =200x
Divide both sides by 200
2.4=x
So, it would take 2.4 hours.
