Problem 4.3, C&S.

A. Make a graph showing Sascha's total distance traveled over time. Use 5-minute intervals on the x-axis.

B. How far did Sascha travel in his 1-hour ride? Explain.

Sascha traveled 26.23 miles in his 1-hour bike ride. For each 5-minute interval I added the distance he traveled, I calculated the distance by dividing his speed by 12 because there are 12 X 5 min = 60 min. per hour.

C. If you could maintain a steady speed of 13 miles per hour on a bike, how long would it take you to travel the same distance sascha traveled?

It would take me just over 2 hours at 13 mph.

D. If you were racing Sascha, what constant speed would you have to maintain to tie him?

I would have to maintain a steady speed of 26.23 mp/h to tie with Sascha.

F.U.

Can you write a single equation that will allow you to predict Sascha's total distance at any time during his 1-hour ride?

No, because his speed is not constant, so there is no single equation.
