Answer:
300 mph
Step-by-step explanation:
Let s represent the initial speed of the plane in miles per hour. Then s-40 is the reduced speed after encountering the head wind. The time spent flying against the head wind was 5 - 2 = 3 hours.
... distance = speed×time
... 1380 = s×2 + (s -40)×3
... 1380 = 5s -120 . . . . . . . . . eliminate parenthses
... 1500 = 5s . . . . . . . . . . . . . add 120
... 300 = s . . . . . . . . . . . . . . . divide by 5
