Explanation:
1. Average Speed formula is
[tex]s = \frac{d}{t} [/tex]
As the distance increases, and the time remains constant, thr speed increases as well
2. Forces cause object to speed up or slow down by extering a greater force on a object than its force that opposes it. For example, if a person is running. The pushing force ( the person using their legs to run) is greater than the friction force. which is from the ground.
