Problema Solution
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 provided by our tutors
x/8.5 + x/8.0 = 99
x[(16+17)/136] = 99
x = 408 meter
Time for lap1 = 408/8.5 =48 sec
Time for lap1 = 408/8 =51 sec
