Answer:
To run 1 mile it will take 1/3 of an hour or 20 minutes
Explanation:
We can use ratios. Take the number of miles and divide by the number of hours
3 miles 1 miles
------------- = -------------
1 hours x hours
Using cross products
3x = 1 * 1
Divide each side by 3
3x/3 = 1/3
x = 1/3 hours
We know 1 hour = 60 minutes
1/3 of 1 hours = 1/3 *60 = 20 minutes
To run 1 mile it will take 1/3 of an hour or 20 minutes
