Uniform acceleration (velocity-time graphs)
A train accelerates uniformly from rest to a speed v m/s. It continues at this speed for a period of time and then decelerates uniformly to rest. In travelling a total distance d metres the train accelerates through a distance pd metres and decelerates through a distance qd metres, where p < 1 and q < 1. (i) Draw a speed-time graph for the motion of the train. If the average speed of the train for the whole journey is , find the value of b.
The answer is 1.

@Olamide Ogunlade, this problem may not be necessary because I can solve your previous similar problem with lesser information. I have also edited the previous problem in LaTex. Just use the previous one. It is inconvenient for me to post a solution because I am using a phone.
