Serena’s average speed during her training run was 8 kilometers per hour over the 2 hours that she ran. What was the total distance that she ran? Use the formula d = rt, where d represents the distance, r represents the rate, and t represents the time.

Step-by-step explanation:

We know she ran 8 kilometers per hour. She ran for a TOTAL of 2 hours. To find out how many kilometers she ran, you would multiply 8 kilometers times 2 hours. This would get you the distance of 16 kilometers. Serena ran 16 kilometers on her training run.

Formula Form:

We have been given the formula d = rt, where d represents the distance she ran, r representing the rate, and t representing the time. Now we have to fill in those values. We have already calculated the distance which is 16 kilometers, so we will fill that in as d: 16 = rt. Now, the rate she is running is 8 kilometers per hour. Let's fill that in. 16 = 8t. Now we have to fill in the last value which is how long she ran for, in other words the time. In the question it states that Serena ran for 2 hours. That gives us our last value. 16 = 8(km)2(hr)

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
