Question

Ava wants to figure out the average speed she is driving. She starts checking her car’s clock at mile marker 0. It takes her 4 minutes to reach mile marker 3. When she reaches mile marker 6, she notes that 8 minutes total have passed since mile marker 0.

What is the average speed of the car in miles per minute?

Answer 1

Speed is 0.75

Equation is n-6= 0.75(t-8)

Answer 2

The average speed of the car is 0.75 miles per minute.

Explanation:

Ava starts checking her car’s clock at mile marker 0. It takes her 4 minutes to reach mile marker 3.

When she reaches mile marker 6, she notes that 8 minutes total have passed since mile marker 0.

We will find the slope of the function in the given interval to get the average speed.

`V=(y2-y1)/(x2-x1)`

Putting the values we get;

`V=(6-3)/(8-4) =(3)/(4)`

or V = 0.75

Therefore, the average speed of the car is 0.75 miles per minute.
