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
