A car travels along a straight line at a constant speed of 48.5 mi/h for a distance d and then another distance d in the same direction at another constant speed. The average velocity for the entire trip is 32.0 mi/h.
(a) What is the constant speed with which the car moved during the second distance d?
Your response differs from the correct answer by more than 10%. Double check your calculations. mi/h
(b) Suppose the second distance d were traveled in the opposite direction; you forgot something and had to return home at the same constant speed as found in part (a). What is the average velocity for this trip?
(c) What is the average speed for this new trip?
Your response differs from the correct answer by more than 10%. Double check your calculations. mi/h
