Respuesta :
The distance to be covered by the runner is given as 7/8. miles.
The speed of the runner is 3/8 miles per minuet.
The Time taken can be calculated by this formula;
Time = Distance ÷ speed
So, the time taken; 7/8 ÷ 3/8
Time = 7/8 x 8/3 = 7/3.
Time = 2.33 minutes = 2 + (.33 x 60) { 1 minute = 60 seconds}
Time = 2 minutes 20 seconds.
