Step-by-step explanation:
To find the number of minutes it takes Jason to run a mile, we have to first find the rate at which he runs.
This is called Jason's speed. It is given as


From the formula of speed, time is given as:

Time taken for Jason to run 1 mile (1760 yards) will therefore be:

Converting this time to minutes yields:
60 seconds = 1 minute
300.34 equals:

It takes Jason 5 minutes to run 1 mile.
