Since the first train has been travelling for 3 hours, we have the following equations:
d=50t+3*50=50t+150
d=60t

We want to know when they will be equal, so set these equal to eachother:
60t=50t+150
10t=150
t=15

So 15 hours after the second train leaves, they will be at the same distance. This is at 8AM since the second train leaves at 5PM.

notsponge [240]

Extraneous solutions are the values that we get when solving equations which aren't really solutions to the equation.

<h3>What are extraneous solutions?</h3>

Your information is incomplete. Therefore, an overview will be given.  An extraneous solution is the root of a transformed equation which is not a root of the original equation since it was excluded from the domain of the original equation.

The reason extraneous solutions exist is simply that some operations produce extra answers, and these operations are a part of the path to solving the problem.

Find a number such that its two-third is equal to 5/4
levacccp [35]

Answer:

x = 15/8.

Step-by-step explanation:

Create an equation, let the number be x:

2/3 * x = 5/4

Now we multiply both sides by 3/2

3/2 * 2/3 x = 5/4 * 3/2

x = 15/8.
