Question

PLEASE THIS IS DUE AT MIDNIGHT LOL:

Answer 1

Answer:

• 186.55 mph

Step-by-step explanation:

Let the speed of the plane be s

The speed of the plane in the same direction is

• s + 12

The speed of the plane against wind is

• s - 12

Time = distance/speed

• 455/(s + 12) = 400/(s - 12)

Solving for s

• 400(s + 12) = 455(s - 12)
• 400s + 400*12 = 455s - 455*12
• 455s - 400s = (400 + 455)*12
• 55s = 10260
• s = 10260/55
• s = 186.55 mph

Answer 2

if a plane flies 455 miles with wind, and takes 400 against the wind, and the wind is blowing at a speed of 12mph, then the plane can fly 2455 miles if it's still in the air
