Question

equation represents the distancetraveled against the wind?ProblemAt full speed, Hal travels 600 miles in 2 hourswith the wind. The same distance againstthe wind takes 3 hours.What's the maximum speed of Hal's airplanein still air? What's the speed of the wind?Click on the correct answer.3(x - y) = 6003(x + y) = 600x-speed of the airplane in still airy speed of the wind2(x - y) = 6002(x + y) = 60080888Ma

Answer 1

Take into account:

x = speed of the airplane

y = speed of the air

consider that the product in between time and speed is equal to the distance traveled in the time.

Then, if the airplane took 3 hours complete 600 miles, agaist the wind, you have that the distance traveled by the airplane is 3x without wind. The speed of the wind decelerates the airplane. The "distance traveled by the wind is 3y"

Then, when you subtract the previous terms you obtain:

3x - 3y = 600 factorize 3 left side

3(x - y) = 600
