Question

If 8.5 of a uniform rod weighs 30.6 kg what will be the weight of 5 metre of the same rod

Answer 1

Answer:

18 kg

Step-by-step explanation:

weight of 8.5m rod = 30.6 kg

weight of 1m rod = 30.6 / 8.5 kg

306 × 10 / 85 × 10 kg

306 / 85 kg

3.6 kg

weight of 5m rod = 3.6 × 5

18 kg

Answer 2

Answer:

Step-by-step explanation:

Length=8.5m and 5m

Weighs=30.6kg and x kg

8.5m:5m=30.6kg: x kg

Therefore,

Product of extreme = product of means

8.5m * x kg = 30.6 kg * 5m

X = 306kg * 5m *10/ 85m *10

So, x = 18 kg
