Answer:

Step-by-step explanation:

FIRST:

we divide 124 by 4 because in 4 minutes he can type 124 words, and we need to figure out how many he can type in a minute.

124 divided by 4 is 31. (they can type 31 wpm)

NEXT: now we know they can type 31 wpm, we need to multiply that number by 60 because there are 60 minutes in an hour.

31 x 60 = 1,860

therefore, they can type 1860 words per hour

hope i helped have a great day/night! :'')

Calculate the slope of the line on the graph

Tamiku [17]

Answer:

3.5 (meters per second)

Step-by-step explanation:

To calculate the slope, we need two points. Let's see if we can select two points from the graph.

From the graph, we can pick out two possible points.

At the beginning, (0,2.5) is a valid candidate.

And at the end, with (5,20). Thus, let's use the slope formula to calculate the slope.

The slope formula is:

$m=\frac{y_2-y_1}{x_2-x_1}$

Let (0,2.5) be x₁ and y₁ and let (5,20) be x₂ and y₂. Thus:

$m=\frac{20-2.5}{5-0}$

Simplify:

$m=\frac{17.5}{5}\\ m=3.5$

Thus, the slope is 3.5 meters per second.

Further notes:

And the entire equation will be:

$m=3.5s+2.5$
