Answer:400 miles per hour
Step-by-step explanation:
Let w = speed at which the plane travelled west
Let s = speed at which the plane travelled south
Distance moved in 5 hrs heading west = 5*w = 5w
Distance moved in 4 hrs heading south = 4*s = 4s
Total distance, 3444= 5w + 4s
w = s + 39( 39 miles/hr faster)
5(s+39) + 4s = 3444
5s + 195 + 4s = 3444
9s = 3249
s = 361 miles per hour
w = s + 39 = 361 +39
= 400 miles per hour
