A small plane flies for 3 hours to an airport 450 kilometers away against a strong headwind. The plane then returns to its starting location flying with the wind, taking 2 hours. The wind speed remains constant for the round-trip flight. Which set of equations represents this scenario, where p represents the speed of the plane, and w represents the speed of the wind?

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
