Question

What is the different between jumping jacks per minute

Answer 1

Given a table and a figure of a line.

The table represents the number of jumping jacks per minute for Alicia

So, the unit rate for Alicia =

`(30)/(1)=30`

So, the number of jumping jack per minute for Alicia = 30

The line represents the number of jumping jacks for Melissa

To find the number of jumping jacks, we will find the slope of the line:

As shown the line passes through the points ( 0,0) and ( 4, 100 )

So, the number of jumping jacks for Melissa = 100/4 = 25

So, the difference between them = 30 - 25 = 5 jacks per minute

So, the answer will be the difference = 5
