Question

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

Answer 1

Answer:

24 hours

Step-by-step 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

Answer:

24 hours.

Step-by-step explanation:

We will solve this problem by unitary method.

∵ Time taken to type 6 memos = 3 hours

∴ Time taken to type 1 memos = $\frac{3}{6}$ hours

∴ Time take to type 48 memos = $\frac{3}{6}$ × 48

                                                 = $\frac{1}{2}$ ×  48

                                                 = 24 hours

It will take 24 hours to type 48 memos.
