Question 1
SEAMO self-study edition 2027; not an official 2027 paper. Original source years are retained. 25 questions, 90 minutes; Q1–10: 3 points, Q11–20: 4 points, Q21–25: 6 points, total 100. Original response types and all subparts are preserved. Verified is an editorial convention; source defects, necessary assumptions and unresolved mathematical uncertainty are disclosed.
Car A takes 6 hours to travel from Town A to Town B. Car B takes 8 hours to travel from Town B to Town A. They meet 35 km from the midpoint of the two towns. What is the distance between Town A and Town B, in km?
Practice assumption: both cars leave their respective towns at the same time, travel towards each other and maintain constant speeds. The printed source does not explicitly state these conditions; without them the distance is not determined.
