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?

  • Algebra -

    if the times are x and 99-x, then since the distances are equal, then

    8.5x = 8.0(99-x)
    x = 48

    the laps took 48 and 51 seconds
