7 minutes is the time can you afford to walk
<em><u>Solution:</u></em>
Given that, train is leaving in 11 minutes and you are one mile from the station
Let "x" represent how much time can you afford to walk
Then, (11 - x) is the time you run
You can walk at 4mph and run at 8mph
<em><u>Convert to miles per minute</u></em>
1 hour = 60 minutes

We know that,

Given that, you are one mile from the station
Therefore,
1 mile = distance walk + distance run

Thus, 7 minutes is the time can you afford to walk
