Spike's Calculators

Calculate the time it takes to ride, walk, swim, or run a certain distance in kilometres based on a speed in feet per second.

Feet per Second/Kilometres

- enter the distance in kilometres
- the speed in feet per second

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

time = distance ÷ speed

one kilometre (km) = 0.621371192237334 miles (mi) one kilometre (km) = 3280.83989501312 feet (ft) one hour (hr) = 3600 seconds (sec) one foot per second (ft/sec) = 0.3048 metres per second (m/sec)

How long will it take to run 10 kilometres at a speed of 4 feet per second?

First, convert the 10 kilometres to a distance in feet;

3280.83989501312 * 10 = 32808.3989501312

10 kilometres equal 32808.4 feet

Divide the distance of 32808.4 feet by the speed of 4 feet per second to get the time in seconds;

32808.4 ÷ 4 = 8202.0997375328

It will take 8202.1 seconds to travel the 10 kilometres at a speed of 4 feet per second.

Convert to decimal hours by dividing by 3600 ( there are 3600 seconds in one hour);

8202.1 ÷ 3600 = 2.2783610382035555555555555555556

The time in hours equals 2.27836 hr. 2 hr - 16 min - 42 sec
