Final answer:
It will take an airplane traveling at 625 miles per hour approximately 5.2 hours to travel 3,250 miles, assuming a constant speed.
Step-by-step explanation:
To calculate how long it will take an airplane traveling at 625 miles per hour to travel 3,250 miles, you can use the formula for time which is time = distance ÷ speed. In this case, the distance is 3,250 miles and the speed of the airplane is 625 miles per hour.
The calculation will be as follows:
Time = 3,250 miles ÷ 625 miles/hour = 5.2 hours
Therefore, it will take the airplane approximately 5.2 hours to travel 3,250 miles, assuming it maintains a constant speed of 625 miles per hour throughout the journey.
