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?

Answer 1

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.
