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 = 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)
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 -
