I was asked the above question in this comment. I understand many students are facing the challenge in sketching distance-time graph given speed-time and vice versa. I have prepared 2 videos to share with you what I taught my students in my weekly coaching programme.
Video 1: Convert Speed-time graph to Distance-time graph.

Video 2: Convert Speed-time graph to Acceleration-time graph.(3min)
(I'm sorry there's an error in the video at time 2:10s, the acceleration should be -6)
