You are one mile from your home. You can walk at a speed of 4 miles per hour. The subway comes by every 15 minutes, and you heard one come by 3 minutes ago. The subway ride takes 8 minutes.
How many minutes will it take to get home by subway if you take the next train?
---------------------
It will be 12 minutes before another train comes along.
Are you going to keep walking during those 12 minutes?
If you don't move the train will need to take you 1 mile.
Saying "the subway ride takes 8 minutes" does not tell
you how long it will take the train to cover one mile.
You need more information.
Cheers,
