A $$1 kg$$ particle exists in a 1-dimensional coordinate system. At time $$t = 0$$, the particle is at rest at $$x = 0 \, m$$. It experiences a force (in Newtons) described by the following equation:

$\large{F(x,t) = 3xt + 1}$

At what time (in seconds) does the particle reach $$x = 4 \, m$$? Give your answer to 2 decimal places.
