Final answer:

The time it would take for the airplane to reach its destination is 5.95 hours. The airplane's speed in miles/hour is 490.82 miles/hr.

Step-by-step explanation:

To calculate the time it would take for an airplane to reach its destination, we can use the formula:

Time = Distance / Speed

Given that the distance is 4,700 km and the speed is 790 km/hr, we can substitute these values into the formula:

Time = 4,700 km / 790 km/hr = 5.95 hours

To find the airplane's speed in miles/hour, we can use the conversion factor:

1 km/hr = 0.621371 miles/hr

Therefore, the airplane's speed in miles/hour is:

790 km/hr * 0.621371 miles/hr = 490.82 miles/hr

Time = (distance) / (average speed)

Time = (4,700 km) / (790 km/hr) = 5.9494 hours (rounded)

= 5hrs 56min 58 sec (rounded)


(4,700 km) / (1.609344 km/mile) = 2,920 miles


Speed = (distance covered) / (time to cover the distance)

(2,929 miles) / 5.9494 hours) = 491 miles per hour
