Answer:
45km/h
Step-by-step explanation:
Seeing as we are starting from 27km/h, we must measure from the lower quartile (the start of the box). Using the knowledge that each section of a box plot constitutes 25% of the values measured, we can deduce that this means we have to count 2 separate areas in a box plot. Since we started on the beginning of the box, and that there are 2 sections in this bx, we must look at the upper quartile now (the end of the box). Measuring this, we get 45km/h.
