How long will it take for an aircraft to fly 720 km if its speed is 160 m / s?

The aircraft travel time can be calculated using the formula:
t = S / V, where t is the aircraft flight time (s), V is the aircraft speed (V = 160 m / s), S is the distance covered by the aircraft (S = 720 km = 720 * 10³ m).
Let’s calculate the flight time of the plane:
t = S / V = 720 * 10³ / 160 = 4500 s = 75 min.
Answer: The flight time of the aircraft is 75 minutes.
