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

e) none of the above because the measure of angle cba is 101°

50
