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

Answer:

4 minutes = mile mark 3

8 minutes = mile mark 6

the constant of proportionality is both 3/4 so the answer is 3/4 miles per minute
