Question 382067: Jamie ran two laps around a track in 99 s. How long did it take him to run each lap if he ran the first lap at 8.5 m/s and the second at 8.0 m/s? Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! Let t=time of the 1st lap.
speed * time = speed * time
8.5t = 8.0(99-t)
8.5t=792-8t
16.5t=792
t=48s
99-48=51s time of the 2nd lap.
