Question

a metal pipe 5 metre long was found to weigh 7.5 kg. What would be the weight of the same kind of 2 m long pipe?

Answer 1

Answer:

Metal pipe (5 metre long) - weight = 7.5  kg

So, we need to find the weight of 1m long metal pipe = $\frac{7.5}{5\\}$ = 1.54 kg

Therefore, weight of 2m long metal pipe "same kind" = 1.54 × 2 = 3.08 kg

Answer 2

Answer:

answer

Step-by-step explanation:

The weight of 3 meter long pipe = 7.6kg

∴ The weight of 1 meter long pipe = 7.6/3kg

Thus, weight of 7.8 meter long pipe =7.6/3kg=2.6×7.6 kg=19.76kg
