Section of a pipe's length and weight are in proportion. if 2.5 m of pipe weighs 10 kg, then a) 5 m of pipe weighs 30 kg. b) 5 m of pipe weighs 40 kg. c) 10 m of pipe weighs 40 kg. d) 10 m of pipe weighs 80 kg.

We will proceed to resolve each case to determine the solution.

we know that

m of pipe weighs kg

so

by proportion

Find the weighs of each case

case A) m of pipe weighs kg

therefore

The statement case A) is False

case B) m of pipe weighs kg

therefore

The statement case B) is False

case C) m of pipe weighs kg

therefore

The statement case C) is True

case D) m of pipe weighs kg

therefore

The statement case D) is False

therefore

the answer is

m of pipe weighs kg
