1 Robert throws a frisbee to Grace, who is 50m away. It reaches her in 5s. What was the speed of the frisbee? Include the correct units in your answer.
Robert threw the Frisbee at 10 m/s. This is because the formula for average speed is: v = d/t v = Average speed or average velocity d = Distance t = Time so the formula would say v = 50m/5s; v = 10m/s
