Question

If 8.5m of a rod weighs 30.6 kg. What will be the weight 5m of rod​

Answer 1

18kg

Explanation:

we're going to use the concept of direct proportions which states that x1/y1=x2/y2

here we have x1= 8.5m we have y1= 30.6 kg and we have x2=5m

`(8.5m)/(30.6kg )=(5m)/(y_(2) )`

then cross multpliy

8.5y=153

divide

=18 kg
