If 22.5 metre of a uniform iron rod weight 85.5 kg , what will be the length of 22.8 kg of the same rod?

6 meters

Step-by-step explanation:

You need to find the rate of kilograms per meter.

Using the given information, there are 85.5 kilograms in 22.5 meters.

simplify to a denominator of 1:

=

3.8 kilograms per meter.

Now you can write an equation:

3.8 × L = K, where L is length and K is weight in kilograms

Weight is given: 22.8kg

Plug in length for K in the equation:

3.8 × L = 22.8

Solve for L:

L =

L = 6

40 minutes

step-by-step explanation:

add the time and multiply by 2
