train math
Can someone please help me in my math homework?
I only have two math problems. – Trains # 1 two-day trip at the same place, move in opposite directions directions to 6 hours. After 3 hours, is 414 miles away. What is the speed of each trip, if the pace of a train is 8 mph over faster than the other? – # 2 Two trains travel of eleven hours, from the same point traveling in opposite directions. A train traveling at an average rate that is 11 miles Hour by parents than the other. Find the rate of each train if they are 635 miles apart after 5 hours.
# 1 let R1 = R2 = x Let x 8 DT = D1 + D2 414 = R1 + R2 * Q1 * Q2 * 414 = x 3 + (x +8) * 3 = 3 x 414 + 3x + 24 414 = 24 + 6 x 390 = 6x x = 65 trains first is 65 mph 2 train is to 73 mph # 2 let R1 = R2 Let x = x 11 = DT D1 + D2 635 = R1 + R2 * Q1 * Q2 * 635 = x 5 + (x +11) * 5 635 = 5 + 5x + 55 580 = 10x x = 58 I hope that help <3 Janine first train 2 is 58 mph train is 69 mph
