Question

a bike travels 42 miles in 6 hours at a constant speed. the constant of proportionality (miles per hour) is
mph

Explanation:

Step1: Recall speed formula

Speed (constant of proportionality here) is distance divided by time, so \( \text{Speed} = \frac{\text{Distance}}{\text{Time}} \).

Step2: Substitute values

Distance is 42 miles, time is 6 hours. So \( \text{Speed} = \frac{42}{6} \).

Step3: Calculate the result

\( \frac{42}{6} = 7 \).

Answer:

7
