Question

It takes 3 hours to type 6 memos. How long will it take to type 48 memos?

Answer 1

24 hours

Explanation:

First find Unit Rate which is, 6 ÷ 3 = 2 memos per hour.

2. We know she writes 2 memos in one hour so, \frac{hour}{memos} , \frac{1}{2} = \frac{?}{48} .

? is equal to 24 hours since 48 ÷ 2 = 24

Answer 2

24 hours.

Explanation:

We will solve this problem by unitary method.

∵ Time taken to type 6 memos = 3 hours

∴ Time taken to type 1 memos =
`(3)/(6)` hours

∴ Time take to type 48 memos =
`(3)/(6)` × 48

=
`(1)/(2)` × 48

= 24 hours

It will take 24 hours to type 48 memos.
