Algebra problem: two speeds
Photo courtesy of Ben Cooper The speed of a freight train is 14km/h slower than the speed of a passenger train. The freight train travels 330 km, in the same time that it takes a passenger train to travel 360 km. Find the speed of each train. Again, an algebra problem about speeds. Again, we will make a simple table about the two trains. The table will have columns for speed, distance, and time. | distance | speed | time ----------------------------------------------- Freight train | 330 | v | ------------------------------------------------- Passenger train| 360 | v + 14 | Notice the problem says "in the same time". Let's call that t. | distance | speed | time ----------------------------------------------- Freight train | 330 | v | t ------------------------------------------------- Passenger train| 360 | v + 14 | t Of course, the goal is to have an equation in a single variable, not in two varia...
