Question

Riley measured the distance her friend Blakely ran on a straight track every 2 seconds. What was Blakely's average speed? What was her acceleration?

Answer 1

Average speed = 25m/s

Acceleration = 12.5m/s^2

Step-by-step explanation

Let the distance covered by Riley be 50m

Average speed = Distance/Time

Average speed = 50/2

Average speed = 25m/s

Acceleration = Speed/time

Acceleration = 25/2

Acceleration = 12.5m/s^2

Note that the value of the distance was assumed
