Cars A and B are travelling in the same direction along a straight road.
The time t is in seconds. At t = 0, car A is at rest. It accelerates at 3 ms-1 for 01t ≤≤ and then travels at a constant speed.
Car B travels at 15 ms-1 for 03t ≤≤ and then accelerates at 1 ms-2 until it reaches a speed of 25 ms-1, after which it continues at this constant speed.

Given that car A is 500 m behind car B at t = 0, at what value of t does car A catch up with car B?

It doesn't if RoyalSheepy is driving; it ends up in a ditch long before then.
