Time from Distance in Miles and Speed in Feet per Second

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

Time from Speed and Distance
Feet per Second/Miles

Distance in Miles mi
Speed in Feet per Second m/sec


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


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


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

time = distance ÷ speed
one mile (mi) = 1.609344 kilometres (km)
one mile (mi) = 5280 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 walk 10 miles at a speed of 3 feet per second?
First, convert the 10 miles to a distance in feet;
5280 * 10 = 52800
10 miles equals 52800 feet

Divide the distance of 52800 feet by the speed of 3 feet per second to get the time in seconds;
52800 ÷ 3 = 17,600 
It will take 17600 seconds to travel the 10 miles at a speed of 3 feet per second.

Convert to decimal hours by dividing by 3600 ( there are 3600 seconds in one hour);
7600 ÷ 3600 = 4.8888888889
The time in hours equals 4.8888888889 hr. = 4 hr - 53 min -
