7. A student on the cross-country team runs 30 minutes a day as a part of her training,
Write an equation to describe the relationship between the distance she runs in
miles, D, and her running speed, in miles per hour, when she runs:
a. at a constant speed of 4 miles per hour for the entire 30 minutes​

Answer 1

Answer:

The required equation is $D=0.5(4)$

Step-by-step explanation:

Consider the provided information.

Student on the cross-country team runs 30 minutes a day as a part of her training,

30 minutes = 0.5 hours

As we know $Speed=\frac{Distance}{Time}$

Let the distance she runs in miles, is represented by D, and her running speed, in miles per hour is represented by S.

Therefore, the required equation is: $S=\frac{D}{0.5}$

Part (A) At a constant speed of 4 miles per hour for the entire 30 minutes​.

Substitute S=4 in above equation.

$4=\frac{D}{0.5}$

$D=0.5(4)$

$D=2$

Hence, the required equation is $D=0.5(4)$
