A car is moving at a fixed speed. The distance D that the car covers is then directly proportional to the time T it moves.

Find the speed of the car. Write a formula that connects D and T. What is the coefficient of variation k equal to?

If D=20 miles when T=15 minutes, write a proportion to find D for T=20 minutes

I'm not quite sure what questions you want answered so I tried my best

For speed convert 15 minutes to. 25 of an Hour so divide 20 by. 25 to get a speed of 80 miles per house

A formula that connects Distance and Time would be Speed=Distance/Time, Distance = Speed * Time, Time = Distance / Speed
