Solve the all parts of given problem:

Problem: Running on a treadmill is slightly easier than running outside because there is no drag force to work against. Suppose a 60 kg runner completes a 5.0 km race in 19 minutes.

Part I: Determine the drag force on the runner during the race. Suppose that the cross section area of the runner is 0.72 m² and the density of air is 1.2 kg/m³.

Part II: What is this force as a fraction of the runner's weight?

I want help to find this force as a fraction of the runner's weight.
