Answer:
33.75 m
Step-by-step explanation:
We can first draw a sketch of the velocity-time graph of the skater to better visualise the motion. From the above graph, we can see that the total distance travelled is just the Area of A and B. Hence:
Total Distance Travelled = Area of A + Area of B
= (0.5)(4.5)(5.0) + (4.5)(5.0)
= 33.75m
