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) Divide both sides of equation by t to isolate r. Then, r = d/t

B) Plugging in the given numbers, solve r = 760,320 yards / 2 hours = 380,160 yd/hr

C) Looking up the conversion from yards to miles, 1 yard = (1/1760) miles. Then multiply by our answer in (B) by that ratio => (380,160 yd/hr)*(1 mile/1760 yd) = 216 mi/hr

D) Use miles in this scenario because of the number of significant digits (yards would require a number in the hundred-thousands).

answer: the answer is d

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
