Let the distance be x Speed =. ( distance / time ) Distance = speed * time 6t + 90 = 8t -200 2t = 290 T =145 t - 25 = 120 = 2 hrs 120 + 15 = 135 135/60 * 6 = d D = 13.5 km

use him1618 equations and solve for d using either substitution or elimination t = d/6 - 1/4 -> (d/6 - 1/4) -5/12 = d/8

-1/4 - 5/12 = d/8 - d/6 -3/12 -5/12 = 6d/48 - 8d/48 -8/12 = -2d/48 -2/3 = -d/24 48/3 = d 16 = d
