The time plane will take to travel 1050 miles into the wind is 2.5 hours.
Speed is defined as the rate of change of position in unit time.
Mathematically,
Speed = Distance/Time
Now given that,
Speed of airplane in still air = 450 mph
Speed of wind = 30 mph
Distance to travel = 1050 miles
So, Actual speed of wind = 450 mph - 30 mph
⇒ Actual speed of wind = 420 mph
So, since Speed = Distance/Time
⇒ Time = Distance/Speed
⇒ Time = 1050/420
⇒ Time = 2.5 hours
Thus, the time plane will take to travel 1050 miles into the wind is 2.5 hours.
