Solving the system of equations, it is found that a viable time that the trains are side by side is given by:
B. 15 sec
<h3>What is a system of equations?</h3>
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:
They will be side by side when:
It's solution is a quadratic function with coefficients a = 14, b = -130, c = -1200, hence:
Time is a non-negative measure, hence option B is correct.
