Doug and Dan can fill 60 orders in 3 hours. How long will it take to fill 85 orders?

Hourly Rate × Hours = Orders Filled

I would begin by calculating how many orders Doug and Dan fill per hour. That's their hourly rate. (Let us know, if you need help calculating that rate.)

I could then define a variable, to represent the unknown hours:

Let t = the hours that Doug and Dan worked

Using the hourly rate, the variable t, and the number of orders filled, I could then write an equation to solve for t.

(hourly rate) (t) = 85

Please show any work that you can, if you would like more help. Or, ask specific questions, if you get stuck. Thanks.

There are several ways you might solve problems like this. Another is to write and solve a proportion, 60:3 = 85:x or another like it.Doug and Dan can fill 60 orders in 3 hours. How long will it take to fill 85 orders?

If you tell us what methods you have learned, we can help you apply them.
