Question

yesterday, you typed 8 pages in 48 minutes. Today, you typed 20 pages in 2 hours. what is the rate of typing? Explain

Answer 1

rate is 6 pages/min

Explanation:

48/8=6

2 hours=120 minutes

120/20=6

Answer 2

1 page typed in 6 minutes

Explanation:

The given points are:

(48, 8) and;

(120, 20)

Convert 2 hours to 60⋅2=120 minutes

The rate of typing is

`(8)/(48)` =
`(1)/(6)` pages/minute

and this agrees with the second point:

`(20)/(120)` =
`(1)/(6)` pages/minute

The equation will have to form:

y=m⋅x where m is the slope of the line.

In this case, m =
`(1)/(6)` , so the equation is:

`y=((1)/(6))*x`

From this you can see that when x = 6, y = 1, and that is 1 page typed in 6 minutes.
