Clare spent a total of 25 minutes at the track. she spent 5 minutes stretching and walked 4 laps around the track. if she walked at a constant pace, how long did it take her to walk each lap? what was her pace in inches per second?

She spended 25 minutes at the track:

5 minutes stretching.

and we know that she did 4 laps at a constant rate, we want to know how much time took each lap.

the amount of time that she speend walking is the total amount of time in the track minus the amount of time stretching:

25 min - 5 min  = 20 min

then, the amount of time that each lap needs is the total time divided the number of laps:

t = 20min/4 = 5min

each lap needs 5minutes,

and the pace in inches per second is equal to the lenght of the track divided the time:

suppose that the lenght is 100 meters = 39.37*100 in = 3937 inches

Lenght = 3937 in

time = 5 min = 5*60s = 300s

speed = (3937/300)in/s = 13.12 inches per second

could you give more information?

the answer is 13 cm
