Answer:
Step-by-step explanation:
If v = plane velocity and c = air current, then:
v + c = 480
v - c = 400
2v = 880
v = 440
The plane's velocity in still air would be 440 miles per hour.
Answer:
85.5 miles
Step-by-step explanation:
From the attached diagram, distance between the two rest stops :
Rest stop A to Rest stop B = 2 1/4 inches
Scale factor :
1 in = 38 miles
Acrual distance would be :
2 1/4 inches would be :
2 1/4 * 38 miles
9/4 * 38 = 85.5 miles
