Answer 1

Using a system of equations, it is found that the trains will be side by side in 15 seconds.

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the equations are:

$y_1 = 229t$

$y_2 = 149t + 1200$

They will be side-by-side when:

$y_1 = y_2$

Hence:

$229t = 149t + 1200$

$80t = 1200$

$t = \frac{1200}{80}$

$t = 15$

The trains will be side by side in 15 seconds.
