Spike's Calculators

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

Kilometres per Hour/Miles

- enter the distance in kilometres
- the speed in miles per hour

- the distance in kilometres converted to miles
- the miles per hour converted to kilometres per hour
- the time in decimal hours
- the time in hour, minute, and second format

time = distance ÷ speed

one one kilometre (km) = 0.621371192237334 miles (mi) one mile per hour (mi/hr) = 1.609344 kilometres per hour (km/hr)

How long will it take to drive 120 kilometres at a speed of 45 miles per hour?

First convert the kilometres to miles;

120 * 0.621371192237334 = 74.5645

120 kilometres equals 74.5645 miles

Divide the distance of 74.5645 miles by the speed of 45 miles per hour to get the time in hours;

74.5645 ÷ 45 = 1.65699

It will take 1.657 hours to travel the 120 kilometres at a speed of 45 miles per hour. 1 hr - 39 min - 25 sec
