How much time would it take for an airplane to reach his destination if it traveled at an average speed of 790 km/h for a distance of 4700 km what is the airplane speed in miles per hour?
To find the time it would take for the airplane to reach its destination, we can use the formula: time = distance / speed.
Given that the distance is 4700 km and the speed is 790 km/h:
time = 4700 km / 790 km/h
time ≈ 5.9494 hours
To find the airplane speed in miles per hour, we need to convert the speed from kilometers per hour to miles per hour.
Since 1 kilometer is approximately equal to 0.621371 miles:
speed in miles per hour = 790 km/h * 0.621371 miles/km
speed in miles per hour ≈ 490.87429 miles/hour
Therefore, the airplane speed in miles per hour is approximately 490.87 miles per hour.
