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)

try looking in the very back of the book : )

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
