Question

question 5
a cyclist rides 30 miles in 2 hours.
what is the best estimate of his speed?
21 mph
15 mph
12 mph
18 mph

Explanation:

Step1: Recall speed formula

Speed is calculated as distance divided by time, so \( \text{Speed} = \frac{\text{Distance}}{\text{Time}} \).

Step2: Substitute values

Here, distance is 30 miles and time is 2 hours. Substitute into the formula: \( \text{Speed} = \frac{30}{2} = 15 \) mph.

Answer:

15 mph (corresponding to the option "15 mph")
