Ajet plane traveling at a constant speed goes 1200 mi with the wind, then turns around and travels for 1000 mi against the wind. if the speed of the wind is a constant 50 mph, and the total flight took 4 hours, find the speed of the plane. round your answer to the nearest tenth, if necessary.

Avg speed 550 miles per hour

Step-by-step explanation:

with the wind 1200 miles traveling

1200/(550+50) = 2 hours

Against the wind

1000/(550-50) = 2 hours

56

step-by-step explanation:

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
