At this point you only have to pay attention to one of the objects. You've determined that after 5.9524s they are at the same position, so you can plug 5.9524 into either one of their position equations to get the distance
Plugging into the equation for position of the bike:
Bike Position = 0 + (10m/s)*5.9524s + (.5*0*5.9524s^2)
Plugging into the equation for position of the car:
Car Position = 0 + 0*5.9524s + (.5*3.36m/s^2 * 5.9524s^2)
They will both give you the same answer, since we've already determined that the positions are the same at this t
