The equation is time= distance/rate and the train is going 300 miles the car is going 200 miles the train goes 20 miles faster than the car fitting the numbers into the equation 200/r=300/(r+20) cross multiply 200/r = 300/(r+20) 200(r+20) = 300r distributive property 4000+200r=300r subtract 200r from both sides to add like terms 4000=100r divide 100 from each side to get r by itself 40 = rate of car 60 = rate of train
Take the three and divide it with the 12 which would get you 4 so put a open circle Above the 4 and make the line go to the left I think I hope this will help
