    From your diagram of part 4(a), you should have obtained T=75 for 4(b)

    4(c) at 990m the time is 60 seconds for the car.
    the first part from u=0 to v=22 has an area of 330m. The remaining 660 m is covered in another 30 seconds (at v = 22) so in total the car is at t = 60s.
    The motorcyclist starts 10 secs later so it takes him 50 seconds to arrive at point A
    4(d) s = ut + 1/2 a t^2
    990 = 1/2 a 50^2
    a = 1980/2500 = 0.792 m s^-2
