Answer:
The time taken for the airplane to cover the distance is 15 minutes.
Explanation:
Given;
velocity of airplane, u = 800 km/h
distance traveled by the airplane, s = 200 km
The time of this motion is given by;
s = ut + ¹/₂at²
at constant velocity, acceleration, a = 0
s = ut
t = s / u
t = (200 km) / (800 km/h)
t = 0.25 hour = 15 mins
Therefore, the time taken for the airplane to cover the distance is 15 minutes.
