Question

Max ran 50 meters in 10 seconds. molly ran 30 meters in 5 seconds. who ran faster

Answer 1

To compare their speed (rate), we need to have the same time or same distance to use as a reference.

Matt ran 50 meters per 10 seconds. Molly ran 30 meters per 5 seconds. If she ran for 5 more seconds, she would have gone 30 more meters, for 30 meters per 10 seconds. Thus, Molly went faster.

Alternately, you could calculate their speeds in meters per (one) second and compare. 50 meters per 10 seconds is 5 meters per second, and 30 meters per 5 seconds is 6 meters per second.

Answer 2

Hey there!

Max:

50 divided by 10 = 5 (Meaning that per second, 5 meters were ran)

Molly:

30 divided by 5 = 6 (Meaning that per second, 6 meters were ran)

The number 6 is larger than 5 . . .

6 - 5 = 1

Molly ran faster. She ran 1 meter faster per second.

Hope this helps you.
Have a great day!
