A small plane flies 760,320 yards in 2 hours. Use the formula d = rt, where d represents distance, r represents rate, and t represents time, to answer the following questions. Show your work. Part A: Rearrange the distance formula, d = rt, to solve for rate. (2 points) Part B: Find the plane's rate in yards per hour. (3 points) Part C: Find the plane's rate in miles per hour. (3 points) Part D: Which unit, yards, or miles, makes more sense to use in this scenario, and why? (2 points)

A:

B. 380,160 yards per hour

C. 216 miles

D. Miles, explanation for why

Step-by-step explanation:

For a:

If we have the formula and we want to rearrange the equation so that  we solve for r, we want to isolate r on one side of the equation.

To do this, we can divide both sides by t.

For b:

Now that we know the formula to find the rate, . We can now substitute the values of distance (d, 760,320) and time (t, 2) to find r, our rate.

For c:

To convert yards into miles, we have to divide by 1760, as their are 1760 yards in a mile.

So this is the same as 216 miles per hour.

For d:

We are dealing with extremely large numbers here. This plane flies fast, so our best bet is to express it in the biggest terms possible so our numbers don't get too confusing. This means miles is the best unit to use in this scenario.

Hope this helped!

the answer to that one is b
