As shown in the figure below, April enters a race. She runs leftward 100 m to her horse, then she rides 500 m to her truck, then she drives 1000 m in a total time of 120 s.
1000 m
500 m
100 m
What is April's average speed over the 120 s period?
m

13.33m/s

Explanation:

The average velocity is the ratio of total distance traveled to the total time taken to complete the distance. The International System of Units (SI) unit of velocity is the meter per second (m/s). The Velocity is given by the equation:

Velocity = total distance traveled / total time taken

The total distance traveled = Distance traveled by horse + distance traveled by truck + remaining distance traveled = 100 m + 500 m + 1000 m = 1600 m

Total time taken = 120 s

Velocity = total distance traveled / total time taken = 1600 m / 120 s = 13.33 m/s

Velocity = 13.33 m/s

i'm thinking more like energy
