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)

Step-by-step explanation: Part B: Find the plane's rate in yards per hour.

So rate = yards per hour. That is rate = distance per hour (since yards is a distance).

So r=d/t. Now you have the answer for part a

r=760,320 yards in 2 hours. So r= 760,320 yards / 2 hours

Part A: Rearrange the distance formula, d = rt, to solve for rate.

We already found the answer from part b. You can just divide both sides of d=rt by t and get r = d/t.

There are 5280 ft in 1 mile and 3 ft in 1 yard. Try the rest.

Part D: Im so sorry I dont know this

Step-by-step explanation:

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
