Answer 1

Hi!

You can easily apply the Rule of Three.

1. Known data:

20 pages typed (a) ............................ in 2 hours (b)

380 pages will be typed (c) ............ in X hours

2. Unknown data: X

3. Application of the Rule of the Three:

`X = (bc)/(a)`

X = (380 x 2) / 20X = 760 / 20

X = 38

4. Conclusion:

Miss Reyes will finish typing the full manuscript of 380 pages within 38 hours.

Answer 2

You have to turn the words into a math phrase. It's a lot easier to understand that way.
