Question

Jada has been helping her younger brother practice his math facts all week. Each time they practice, Jada gives her brother 3 minutes to do as many math facts as he can. On Monday, Jada's brother completed 48 math facts. On Tuesday, he did better and completed 57 math facts. How many more math facts per minute did Jada's brother complete on Tuesday than on Monday?

Answer 1

3 facts/minute

Explanation:

hey there,

< It looks like we're finding speed here, and the formula for speed is
`speed = (amount)/(time)`.

On Monday, his amount of math facts was 48, and the time was 3 minutes. Usually, you're supposed to always convert to seconds but here it says "per minute" so we have to keep it that way. Let's find his speed.

`speed = (48)/(3)` = 16 facts/minute

Now, let's find Tuesday's speed.

`speed = (57)/(3) =` 19 facts/minute

Now that we know both speeds on both days, let's find the difference.

19-16 = 3

Jada's brother completed 3 facts/minute more than on Monday. >

Hope this helped! Feel free to ask anything else.
