Question
If the weight of 13 metres long rod is 23.4 kg. What is the weight of 6 metres long rod?
- 7.2 kg
- 10.8 kg
- 12.4 kg
- 18.0 kg
Solution
To find the weight of a 6-meter long rod, we can use the concept of proportionality.
First, we need to determine the weight per meter of the 13-meter long rod. We can do this by dividing the weight of the rod (23.4 kg) by its length (13 m):
Weight per meter = 23.4 kg / 13 m = 1.8 kg/m
Now, we can use this weight per meter value to find the weight of the 6-meter long rod. We multiply the weight per meter by the length of the 6-meter long rod:
Weight of 6-meter long rod = 1.8 kg/m * 6 m = 10.8 kg
Therefore, the weight of the 6-meter long rod is 10.8 kg.
