Earl runs 50 meters in 20 seconds. How many meters does Earl run per second?

Earl can run 2.5 meters in one second.

Step-by-step explanation:

We know that Earl can run 50 meters in 20 seconds. That means he can run 150 meters in one minute and 9,000 meters (or 9 kilometers) in one hour. 50 meters / 20 seconds = ? meters / 1 second

50 meters / 20 seconds = x / 1 second

(50 x 1) = (20) (x)

50 = 20x divide both sides by 20 to get the "x" alone

50 / 20 = x

2.5 = x

I think it's A for the first one and B in the second.
