Question

mike walked 3 miles in 45 minutes. what was his rate in miles per hour? \\(\frac{1}{4}\\) miles per hour \\(2\frac{1}{4}\\) miles per hour 4 miles per hour 15 miles per hour

Explanation:

Step1: Convert minutes to hours

Since 1 hour = 60 minutes, 45 minutes = $\frac{45}{60} = \frac{3}{4}$ hours.

Step2: Calculate rate in mph

Rate = $\frac{\text{Distance}}{\text{Time}} = \frac{3}{\frac{3}{4}}$

Step3: Simplify the expression

$\frac{3}{\frac{3}{4}} = 3 \times \frac{4}{3} = 4$

Answer:

4 miles per hour
