Using a trigonometric equation, it is found that it will take 2.28 minutes until the two trains are first equidistant from the child.
<h3>What is the distance of each train to the child?</h3>
The distance of the first train is:

The distance of the second train is:

<h3>When are the trains equidistant to the child?</h3>
When
, hence:

The following substitution is made:

Hence:


Which is a quadratic equation with coefficients
, hence:



Then, applying the trigonometric equation, considering that
due to the range of the cosine function:


It will take 2.28 minutes until the two trains are first equidistant from the child.
