Practice problem 2. Try solving this problem. It's similar to the problem we just solved. When you're finished, scroll down to see the answer and an explanation. A train moving 60 mph leaves the station at noon. An hour later, a train moving 80 mph leaves heading the same direction on a parallel track.
Two trains leaving the station at different times...
The trick with word problems is to pick them apart to see what you know, then build equations that you can solve. It takes some practice. In this problem, we know that one train starts two hours before the other one and travels at a known rate. Let's calculate how far it goes in those two hours:
Two Trains Puzzle -- from Wolfram MathWorld
Two Trains Puzzle. Download Wolfram Notebook. Two trains are on the same track a distance 100 km apart heading towards one another, each at a speed of 50 km/h. A fly starting out at the front of one train, flies towards the other at a speed of 75 km/h. Upon reaching the other train, the fly turns around and continues towards the first train.
Algebra: Speed and Distance Problems
Solution: Two trains means two distance formulas: D A = r A · t A and D B = r B · t B. Your first goal is to plug in any values you can determine from the problem. Since Train A travels 95 mph, r A = 95; similarly, r B = 110. Notice that the problem also says that the trains leave at the same time. This means that their travel times match ...
ELI5: How do you solve the classic 'two trains leave different cities
I guess if you simply want to know off the top of your head how to solve the problem in a party situation, all you need to know is the amount of distance between the two train stations and the speed at which the two trains are going. Add to two speeds and then divide the distance by this number. For example: The distance between two train ...

Distance/Rate/Time Word Problems
Step 1: start by writing the information from the problem in a table, so we know what we have and what we're missing. First, make columns for distance, rate, and time, and rows for each of the moving objects (such as the two trains in our example problem). Then, fill in all the information that was provided by the problem.
Problems on Trains: Speed, Time, Distance, Formula, Examples
Q.1. How do you solve the problem with \(2\) trains?Ans: For solving the problems related to trains, it is essential to know the relative speed of two trains. If two trains move in the same direction, then the relative speed will be the difference between their speed. If two trains move in the opposite direction, then the relative speed will be ...
how long will it take for the two trains to meet
For train 2, we have this equation: 288 - x = 85t. Use the Substitution Method by replacing x in the equation for train 2 with the value 75t. 288 - 75t = 85t. 288 = 160t. 288/160 = 9/5 = 1 4/5 = 1 8/10 = 1.8 hours. 0.8 hours = 48 min. It will take 1 hour and 48 min. for the two trains to meet. Upvote • 0 Downvote.

Since both trains move toward each other when remaining half of a space, then the general meeting equation in t is: v1 ∗ t +v2 ∗ t = S v 1 ∗ t + v 2 ∗ t = S. Then we get that: St 4 + 2St 7 = S 2 t 4 + 2t 7 = 1 2 t = 14 15(56 minutes) S t 4 + 2 S t 7 = S 2 t 4 + 2 t 7 = 1 2 t = 14 15 ( 56 minutes) Q.E.D. Share.
Solving Problems With a Distance-Rate-Time Formula
Rate is distance per time, so its units could be mph, meters per second, or inches per year. Now you can solve the system of equations: 50t = 100 (t - 2) (Multiply both values inside the parentheses by 100.) 50t = 100t - 200. 200 = 50t (Divide 200 by 50 to solve for t.) t = 4. Substitute t = 4 into train No. 1.
PROBLEMS ON TRAINS WITH SOLUTIONS
Solution : speed = 20 m/sec. To convert m/sec to km/h, multiply the given m/sec by 18/5. = 20 x 18/5 km/hr. = 72 km/hr. Problem 2 : The length of a train is 300 meter and length of the platform is 500 meter. If the speed of the train is 20 m/sec, find the time taken by the train to cross the platform.

Problems on Trains
Solution: To calculate the distance here you need to add the distance traveled by both the trains together. Distance traveled by train A will be: d= s t, the rate at which it travels here is 50mph and the time is 2 hours. So the distance traveled by train A will be 50×2 = 100. Similarly, distance traveled by train B will be 70×2 = 140.
