Time from Distance in Kilo and Speed in Feet per Second

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

Time from Speed and Distance
Feet per Second/Kilometres

Distance in Kilometres km
Speed in Feet per Second ft/sec


Distance in Miles mi
Speed in Metres per Second m/sec
Time in Seconds min
Time in Decimal Hours hr
Time hour min sec


  1. enter the distance in kilometres
  2. the speed in feet per second


  1. the distance in kilometres converted to miles
  2. feet per second converted to metres per second
  3. the time in seconds
  4. the time in decimal hours
  5. 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)
Example Calculation
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
