Time from a Distance in Kilometres and Speed in Kilometres per Hour

Calculate the time it takes to travel a certain distance in kilometres based on a speed of kilometres per hour.

Time from Speed and Distance
Kilometres per Hour/Kilometres

Distance in Kilometres km
Speed in Kilometres per Hour mi/hr


Distance in Miles mi
Speed in Miles per Hour mi/hr
Time in Decimal Hours hr
Time hour min sec


  1. enter the distance in kilometres
  2. the speed in kilometres per hour


  1. the distance in kilometres converted to miles
  2. the kilometres per hour converted to miles per hour
  3. the time in decimal hours
  4. the time in hour, minute, and second format

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)
Example Calculation
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
