An object on a number line moved from x= 15 m to x = 165 m all in a time of 100 seconds. a) What was the average speed of the object?

Answer 1

Speed is the change in distance over time.

The change in the distance is 165 m - 15 m = 150 m, and the time is 100 s.

The speed is 150 m / 100 s = 1.5 m/s.
