Question 30125: Crystal drove from Sarnia at 80 km/h. Emily left Sarnia one hour later and drove along the same road at 100 km/h. How far from Sarnia did Emily overtake Crystal? Answer by checkley71(8403) (Show Source):
You can put this solution on YOUR website! 80 km/h H = 100 km/h (H -1) or 80H = 100(H-1) or 80H = 100H -100
or 100 = 100H-80H or 100 = 20H or H=100/20 or H=5 km/h.
80km/h time 5 H = 400 km & 100km/h times (5-1H) = 400km when Sarnia overtook Crystal.
