The Khan family leaves Kingston once the Maretti family has travelled 40 km, and travels at an average speed of 95 km/h. Determine how far they have travelled when the families have both gone the same distance.Found 2 solutions by stanbon, aaaaaaaa:Answer by stanbon(60771)   (Show Source): You can put this solution on YOUR website!Two families drive from Kingston to Niagara Falls. The Maretti family leaves first and travels at an average speed of 85 km/h. The Khan family leaves Kingston once the Maretti family has travelled 40 km, and travels at an average speed of 95 km/h. Determine how far they have travelled when the families have both gone the same distance. -------------- Maretti family DATA: rate = 85 km/h ; distance = x -40 km ; time=(x-40)/85 hr. ------ Khan family DATA: rate = 95 km/h ; distance = x km ; time=x/95 ---------- EQUATION: Time = time (x-40)/85 = x/95 95x - 3800 = 85x 10x=3800 x=380 km They have both gone 380 km. Cheers, Stan H. Answer by aaaaaaaa(138)   (Show Source): You can put this solution on YOUR website!hours = x distance traveled by Maretti - 85x distance traveled by Khan - 95x However, we know that the Maretti family has a 40 km lead. So: So they'll have traveled the same distance after 4 hours (counting from the moment the Khan family left). That is 95*4=380 km traveled.
