Question

if 22.5 m of a uniform iron rod weighs 85.5 kg,what will be the weight of 5 m of the same rod?​

Answer 1

Answer:

19kg

Step-by-step explanation:

This is a case of direct proportions so

x1/y1 = x2/y2

or 22.5/85.5 = 5/y2

or y2 = 85.5 * 5/22.5

or y2 = 19kg

Answer 2

Answer:

Step-by-step explanation:

Weight of 22.5 uniform rod= 85.5Kg

Weight of 1m rod =88.5/22.5= 35/11 kg

Weight of 5m rod = 5*35/11

= 175/11

=15.9kg (APPROX)
