Depending mainly on payload (how heavy the plane is), the jumbo jet takes off at speeds in the range of 180 to 220 mph (250 to 320 km/h), climbs at about 285 mph under 10,000 feet and from there it accelerates as it goes higher. At cruise altitude (35,000-40000 feet) it goes at Mach 0.85 (that is to say, 85% of the speed of sound) which translates in a ground speed of about 570 mph or 915 km/h, but it can go as fast as Mach 0.92 (614 mph, 988 km/h) should the need arise. Approach speed and landing speed vary according to payload, generally the landing speed being of 195-210 mph (310-330 km/h)
