An airplane that travels 450 mph in still air encounters a 50-mph headwind. How long will it take the plane to travel 1200 mi into the wind?

It takes 3 hours which is equivalent to 180 minutes

Step-by-step explanation:

The actual speed of the wind = 450 -50

= 400mph

D = r*t

D = 1200

r = 400

t = time which is unknown

Inserting into formula

1200 = 400t

Divide through by 400 to get t

1200/400 = t

3 = t

Therefore the time it will take for the plane to travel 1200 mike's is 3 hours from the answer above.

When converted to minutes, 3 hours = 3x60 = 180minutes

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
