Determine speed of man and acceleration of busWatch
The time a faster object overtakes a slower one is at the point where the distance travelled & time taken to travel that distance is the same for both objects. So I tried to make the 2 displacements where t = 30 equal to each other, but I can't exactly 'solve' the equation as I have 2 unknowns: 50 + 450a = 30u
Just catches bus implies their speeds are equal when he gets to the bus

If you only just catch the bus, you must be travelling at the same speed or you will hurt yourself when you hit the road by just missing it.
ONLY JUST is the key in this problem
