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? mi/h(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
