Just draw a velocity-time diagram for the journey.

For part a) think about what equations you need for the acceleration & deceleration phases (middle distance is known)

v = we know
u = we know
a = we know
s = we want
t = we don't care

Is there an equation you can form using the things you know & the thing you want (Hint: yes there is)

Fair enough, it's still a valid approach, however for SUVAT directly you then have to apply v^2=u^2+2as for part A.

Then have to apply two SUVAT equations for the second part at 3 different times. t_1 when it stops accelerating, t_2 when it begins decelerating, and t when it comes to rest again. Drawing a diagram is useful here though.

I'm sure you know how to work out the average speed for the last part with the info you got.
