Answer:
4.5 miles per hour.
Step-by-step explanation:
To make the problem easier and better understand the data, we convert the fractions into decimals, so
2 1/4 miles = (2 + 0.25) thousands = 2.25 miles
1/2 hour = 0.5 hour
To answer we make a simple rule of three
2.25 miles --------------- 0.5 hour
X ----------------------------- 1 hour
X = 2.25 * 1 / 0.5 = 4.5 miles per hour.
I hope this helps!
