Question

Distance between 2 airports 1,505 miles. Average speed of airplane 420 mph. Flight time hours

Answer 1

For this case we have the following definition:
 d = v * t
 Where,
 d: distance
 v: speed
 t: time
 Clearing the time we have:
 t = d / v
 Substituting values:
 t = 1505/420
 t = 3,583 hours
 Answer:
 Flight time hours:
 t = 3,583 hours
