The answer is 2 minutes and 20 seconds.
Here is how its done..
The distance to be covered by the runner is [tex]\frac{7}{8}[/tex] miles.
The speed of the runner is [tex]\frac{3}{8}[/tex] miles per min.
To find the time it took for the runner to finish the race, you can use this formula:
Distance ÷ Speed = Time.
Time Taken: [tex]\frac{7}{8}[/tex] ÷ [tex]\frac{3}{8}[/tex]
Time: [tex]\frac{7}{8}[/tex] * [tex]\frac{8}{3}[/tex] = [tex]\frac{7}{3}[/tex]
Time = 2.33 minutes = 2+(.33x60) [ 1 minute = 60 seconds]
Time = 2 minutes 20 seconds.
I hope this helped you.
Have an amazing day!~
