Answer 1

20 hours

Explanation:

1 jacket=50kg wool

1 jacket= 2hrs

500kg available/50kg per jacket= 10 jackets

10 jackets x 2hrs per jacket=20hrs

Answer 2

Given:

Mark took 2 hours to make a jacket.

The jacket was made up of 50 kilograms of wool.

To find:

The time in which Mark use 500 kilograms of wool for the jackets.

Solution:

We have,

1 jacket take 2 hours.

Number of jackets in 50 kg of wool = 1

Number of jackets in 1 kg of wool =
`(1)/(50)`

Number of jackets in 500 kg of wool =
`(1)/(50)* 500`

=
`10` Jackets

Time taken by 1 jacket = 2 hours

Time taken by 10 jacket = 20 hours

Therefore, it will take 20 hours to use 500 kilograms of wool for the jackets.
