Calculate the time it takes to ride, walk, swim, or run a certain distance in miles based on a speed in metres per second.
time = distance ÷ speed
one kilometre (km) = 0.621371192237334 miles (mi) one mile (mi) = 1609.344 metres (m) one mile (mi) = 1.609344 kilometres (km) one hour (hr) = 3600 seconds (sec) one metre per minute (m/sec) = 3.28083989501312 feet per minute (ft/sec)
How long will it take to run 10 miles at a speed of 2 metres per second?
First, convert the 15 miles to a distance in metres;
10 * 1609.344 = 16093.44
10 miles equals 16093.44 metres
Divide the distance of 16093.44 metres by the speed of 2 metres per second to get the time in seconds;
16093.44 ÷ 2 = 8046.72
It will take 8046.72 seconds to run the 10 miles at a speed of 2 metres per second.
Convert to decimal hours by dividing by 3600 (there are 3600 seconds in one hour);
8046.72 ÷ 3600 = 2.2352
The time in hours equals 2.2352 hr. = 2 hr - 14 min - 7 sec
