Who ran faster? Explain

Question

Max ran 50 meters in 10 seconds and Molly ran 30 meters in 5 seconds.

Answer 1

To figure this out, you need to get the unit rate for each runner

Max: 50 meters/10 seconds = 5 m/s

Molly: 30 meters/5 seconds = 6 m/s

6 m/s > 5 m/s

Molly ran faster than Max

Answer 2

Speed is distance divided by time so we calculate the fastest speed with the data given

50/10 = 5 m/s

30/5 = 6 m/s Molly ran faster, she has the faster rate of speed and covers more distance per second
