Answer:
140 poles
Step-by-step explanation:
1. Convert to the same unit. Either meters to kilometers or kilometers to meters, so you can complete the computation.
- 60 m = 0.06 km (divide by 1,000) - see image #1
2. Divide 0.06 by 8.4 (8.4/0.06 = 140).
3. 140 poles can be placed on the 8.4 km road when separated by 60 m or 0.06 km.
