Question

An airplane that can travel 450 mph in still air, encounters a 30-mph headwind. How long will it take the plane to travel 1050 miles into the wind?

Answer 1

The time plane will take to travel 1050 miles into the wind is 2.5 hours.

What is speed?

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.
