Answer: 0.1km
Explanation:
The first thing to do in order to solve the question is to convert all into thesame units.
100cm = 1m
1000mm = 1m
1000000 mm = 1km
1000m = 1km
A. 3500cm = 3500/100 = 35m
B. 65.5m
C. 75000mm = 75000/1000 = 75m
D. 15.5m
E. 0.1km = 0.1 × 1000 = 100m
Based on the calculation above, the longest distance is 0.1km.
