The position of a passenger train that is traveling at an initial speed of 14 feet per second and continues to accelerate can be
salantis [7]

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:

y = 14t^2

y = 130t + 1200

They will be side by side when:

14t^2 = 130t + 1200

14t^2 - 130t - 1200 = 0

It's solution is a quadratic function with coefficients a = 14, b = -130, c = -1200, hence:

\Delta = (-130)^2 - 4(14)(-1200) = 84100

x_1 = \frac{130 + \sqrt{84100}}{28} = 15

x_2 = \frac{130 - \sqrt{84100}}{28} = -5.71

Time is a non-negative measure, hence option B is correct.
