4/18 = 10/x

x = 45 minutes

Use proportions:
18/4 = x/10
Cross multiply
4x = 180
x = 45 minutes
That's if Valerie doesn't stop to eat some popcorn.

4/18 = 10/x (where x is the number of min to type 10 pages)
4x = 180
x = 45 minutes

Given that "Valerie" seems to think that a good subject line is a row of hearts and the number 3, it'll take her forever.
