In this Kata, we will calculate running pace. To do that, we have to know the distance and the time.
Create the following function:
`runningPace(distance, time)`
Where:
distance - A float with the number of kilometres
time - A string containing the time it took to travel the distance. It will always be minutes:
seconds. For example "25:00" means 25 minutes. You don't have to deal with hours.
The function should return the pace, for example "4:20" means it took 4 minutes and 20 seconds to travel one kilometre.
Note: The pace should always return only the number of minutes and seconds. You don't have to convert these into hours. Floor the number of seconds.
