Takeoff run for a loaded 747 is approximately 30 secs (+ - 5 secs)
Take off speed is approximately 180 knots (+ - 10 knots)
Landing speed is approximately 120 knots (+ - 5 knots)

All from memory of timing a takeoff roll and watching the passenger
flight info screen which displays speed and altitude.

A 747 pilot will tell you for sure
