At t=0 car A and truck B are 350 m apart on a straight road. Starting from rest car A speeds up with a constant acceleration of 10 m/s^2. Truck B is travelling in the opposite direction with a constant speed of 15 m/s. How far away is car A from its starting point when the two vehicles pass each other?

Write equations describing position vs time for both cars separately. Set the positions equal and solve for t. Use that t to compute the location.
Someone here will be glad to critique your work.
