Worked Solution
Step 1: Convert the first distance to metres.
1 km = 1000 m
1 km 600 m = (1 × 1000) + 600 = 1000 + 600 = 1600 m
Step 2: Convert the second distance to metres.
2 km 400 m = (2 × 1000) + 400 = 2000 + 400 = 2400 m
Step 3: Add the two distances.
1600 m + 2400 m = 4000 m
Answer: Wei Lin walks a total of 4000 m.
Correct answer: 4000 m
