Answer 1

The answer to the first one is 16 hours. This is because it is 20 pages per hour, then when you divide 320 by 20, you get 26.
Hope this helps. I was to lazy to do the others.

Answer 2

Explanation:

1. 200 = 10h

320 =

320x10 / 200

= 16h

2. 1.5 = 50m

x = 150 m

150x1.5 / 50

= 4.5cm

3. 4$ = 40balls

x = 100balls

100x4 / 40

= $10
