Calculate the time it takes to travel a certain distance in kilometres based on a speed of kilometres per hour.
time = distance ÷ speed
one mile (mi) = 1.609344 kilometres (km) one kilometre (km) = 0.621371192237334 miles (mi) one kilometre per hour (km/hr) = 0.621371192237334 miles per hr (mi/hr)
How long will it take to drive 220 kilometres at a speed of 70 kilometres per hour?
Divide the distance of 220 kilometres by the speed of 70 kilometres per hour to get the time in hours;
220 ÷ 70 = 3.1428571428571428571428571428571
It will take 3.143 hours to travel the 220 kilometres at a speed of 70 kilometres per hour. 3 hr - 8 min - 34 sec
