Problem-Solving and Data Analysis practice question

A trail is 3.5 kilometres long. What is the length of the trail in metres? (1 kilometre = 1,000 metres)

  1. A. 3,500Correct
  2. B. 350
  3. C. 35
  4. D. 35,000

Answer: A. 3,500

Each kilometre is 1,000 metres, so multiply: 3.5 × 1,000 = 3,500 metres.

Why the other answers are wrong

B. 350
350 is 3.5 × 100. A kilometre is 1,000 metres, not 100 — the decimal point moves three places, not two.
C. 35
35 is 3.5 × 10. Going from kilometres to metres multiplies by 1,000.
D. 35,000
35,000 is 3.5 × 10,000, one zero too many. 1 km = 1,000 m.
