Answer:
7/3 minutes
Step-by-step explanation:
If the runner is 7/8 miles from the finish line, if she can travel 3/8 mile per minute, we can determine the time by taking the inverse of the speed multiplied by the distance left:
[tex]=(8/3)\cdot{7/8}[/tex]
[tex]=7/3[/tex]
The runner takes 7/3 minutes to finish the race.
