The speed, distance and time triangle: Distance on top, Speed and Time on the bottom. Time is covered, leaving Distance over Speed, so Time equals Distance divided by Speed. A drone then flies a 5 kilometre leg at 30 kilometres per hour while a timer runs; the answer is revealed: 5 divided by 30 is 0.167 hours, which is 10 minutes. Units must be consistent: kilometres per hour with hours and kilometres.
