How many more lawns can logan mow per hour thanhow many more lawns can logan mow per hour than brian brian

Answer 1

Logan can mow 1 lawn per hour more than Brian

Explanation:

Given

`Logan: 8\ lawns \to 4\ hours`

See attachment for Brian's graph

First, calculate Logan's hourly rate

`Rate = (Lawn)/(Time)`

`Rate = (8\ lawns)/(4\ hours)`

Rate = 2 lawns per hour

To calculate Brian's rate, we select 2 points from the linear graph

`(x_1,y_1) = (1,1)`

`(x_2,y_2) = (2,2)`

So, the rate is:

`Rate = (y_2 - y_1)/(x_2 - x_1)`

`Rate = (2 - 1)/(2 - 1)`

`Rate = (1)/(1)`

Rate = 1 lawn per hour

So, we have:

`Logan = 2`

`Brian = 1`

Calculate the difference (d)

`d = Logan - Brian`

`d = 2 - 1`

`d = 1`

Logan can mow 1 lawn per hour more than Brian
