Question

Select the correct answer.
Noel works as a driver for a transportation company. On average, he drives 152 hours to make 19 successful deliveries. Assume this rate is his
constant rate for delivering goods. If you graph this relationship with time along the x-axis and number of deliveries along the y-axis, the slope of
the line you get gives Noel's unit rate for a successful delivery. Which unit rate can be interpreted as the slope?

Answer 1

So I have this test too and I'm pretty sure it's 8. I will check back when I know for sure and have my answer submitted.

Edit:

Yes the answer I originally gave is correct.

Answer 2

Noel's unit rate for successful delivery is 1/8 of a delivery per hour option (D) is correct.

What is the rate of change?

It is defined as the change in values of a dependent variable with respect to the independent variables.

The missing options are:

A. 8 deliveries per hour

B. 2/17 of an hour per delivery

C. 1/8 of a delivery per hour

D. 1/8 of an hour per delivery

We have:

On average, he drives 152 hours to make 19 successful deliveries.

The rate is constant.

The total time for which Noel drives = 152 hours

The total number of successful deliveries = 19

Noel's unit rate for a successful delivery

= total successful deliveries/total hours

= 19/152

Divide by 8 on the numerator and denominator:

= 1/8

y = (1/8)x

Here x represents time

y represents the number of deliveries

Thus, Noel's unit rate for a successful delivery is 1/8 of a delivery per hour option (D) is correct.
