To calculate the distance traveled by the plane, we can use the formula:
Distance = Speed × Time
In this case, the average speed of the plane is 610 km/hr and the time of the trip is 2.25 hours. Plugging these values into the formula, we get:
Distance = 610 km/hr × 2.25 hrs
Calculating the product, we find:
Distance = 1372.5 km
Therefore, the plane flies a distance of 1372.5 kilometers.
