Question

Identify the unit rate in the graph     .
A) 60
 B) 120
 C) 180
 D) 240

Answer 1

The unit rate of the graph is A) 60. This is because the graph goes up 60 miles for every hour. Hope this helps!

Answer 2

A) 60.

Explanation:

We have been given a graph of a line and we are asked to find the unit rate for our given line.

Since we know that slope is also known as the unit rate of a function, so let us find slope of our given line.

`\text{Slope}=(y_2-y_1)/(x_2-x_1)`, where,

`y_2-y_1}` represents difference between two y-coordinates.

`x_2-x_1}` represents difference between two x-coordinates of same y-coordinates.

To find the slope we will use points (0,0) and (4,240).

`\text{Slope}=(240-0)/(4-0)`

`\text{Slope}=(240)/(4)`

`\text{Slope}=60`

Therefore, unit rate of our given graph is 60 and option A is the correct choice.
