1. A body travels 10 meters during the first 5 seconds of its travel, and it travel meters over the first 10 seconds of its travel. What is its average speed du from t= 5 seconds to t= 10 seconds? A. 2 meters/second B. 3 meters/second C. 4 meters/second D. 5 meters/second E. 6 meters/second

The answer is C) 4 m/s

Step-by-step explanation:

The average speed between 5s and 10s is 4 m /s

because

Between 5s and 10s the body reached 30m

so Distance traveled : 30m - 10m =20m

And the Speed is : distance/time = 20m/5m = 4m/3

Hope this helps!
