 Question 380457: Two cars travelling in opposite directions were 360 km apart at the end of two hrs. If one car travels 6kph faster than the other, find the average speed of the slower car.Answer by mananth(12270)   (Show Source): You can put this solution on YOUR website!speed of one car = x mph speed of second car = x+6 mph .. they are in opposite directions so add up the speeds x+x+6 = 2x+6 mph. distance = 240 miles .. r=d/t r=240/(2x+6) 2=240/(2x+6) multiply by (2x+60 2(2x+6)=240 4x+12=240 -12 4x=240-12 4x=228 /4 x=57 mph speed of one car speed of other car = x+6 = 57+6 = 63 mph .. m.ananth@hotmail.ca
