train problem - 2 trains going oposite direction leaving from same station - train A going 120 km/hr (velocity)

- train B going 20 km / hr / hr (acceler) Time when are they 500 km apar

What i did was

Trying to solve

[tex] 500= \int_{0}^{t} (20x^2+120x) [/tex]

however when I put that into the solver I am getting negitive answers

with guess and check with the integral I cam out to around 2.549
