Answer:
51 mph
Explanation:
Given: A certain aircraft can fly 612 miles with the wind in 3 hours and travel the same distance against the wind in 6 hours.
Formula:
Let speed of aircraft be x mph and speed of wind y mph
Aircraft along wind:
Actual speed of aircraft = x + y
Time taken = 3 hours
Distance = 612 miles
Aircraft against wind:
Actual speed of aircraft = x - y
Time taken = 6 hours
Distance = 612 miles
By solving equation (1) and equation (2) and we get
x = 153 mph
y = 51 mph
Hence, The speed of wind will be 51 mph
