Select the correct answer.
a body travels 10 meters during the first 5 seconds of its travel, and it travels a total of 30 meters over the first 10 seconds of its travel. what is
its average speed during the time from t = 5 seconds to t = 10 seconds?
a 2 meters/second
b. 3 meters/second
c4 meters/second
d. 5 meters/second
e. 6 meters/second

C. Average Speed = 4 m/s

Explanation:

Average speed is defined as total  distance travelled per unit time taken

From = 5s to = 10 s

Total time = 10 -5 = 5s

Distance travelled in first 5s=  = 10 m

Distance travelled in first 10s = 30 m

Total distance between 5 s- 10 s = 30 - 10 = 20 m
