Answer:
The constant of proportionality in miles per hour is 35.5.
Step-by-step explanation:
The constant of proportionality is Oliver's speed in miles per hour. We can find this by a simple rule of three.
He traveled 124.25 miles in 3.5 hours. So how many miles he traveled in an hour?
3.5 hours - 124.25 miles
1 hour - xmiles
[tex]3.5x = 124.25[/tex]
[tex]x = \frac{124.25}{3.5}[/tex]
[tex]x = 35.5[/tex]
The constant of proportionality in miles per hour is 35.5.
