Question

luis rides his bicycle $\frac{3}{4}$ mile in 15 minutes along the bike trail. assuming he rides at a constant rate, what is his speed, in miles per hour? use the table to help find the answer. enter your answer in the box.

miles	$\frac{3}{4}$	?
hours	?	?

miles per hour

Explanation:

Step1: Convert minutes to hours

Since 1 hour = 60 minutes, 15 minutes = $\frac{15}{60}=\frac{1}{4}$ hours.

Step2: Use speed formula

Speed = $\frac{\text{Distance}}{\text{Time}}$. Given distance $d = \frac{3}{4}$ mile and time $t=\frac{1}{4}$ hour. Then speed $v=\frac{\frac{3}{4}}{\frac{1}{4}}$.

Step3: Calculate the speed

$\frac{\frac{3}{4}}{\frac{1}{4}}=\frac{3}{4}\times4 = 3$ miles per hour.
