7-8 Work Problems

Pre-Ap Algebra 1

Homework Help?

I don't understand how to do these types of problems, could someone please help me, Thanks!

Here are a few... I just don't understand the concept....

1.) Rita takes 3 h to type a report. What part of the typing can she do in 2 h? in x h?

We are supposed to use the formula:

Work rate X time = work done

Thanks Again :)

You can ask one question at a time.

I will answer the first question.

1. Rita can types 1 report per 3 hours.

We need to know the amount of work she does in 2 hours.

We will use ratio.

Let the amount of work be x.

==> 1 report ==> 3 hours.

==> x report ==> 2 hours.

We will cross multiply.

==> 3*x = 1*2

==> 3x = 2

==> x = 2/3

**Then, Rita can types two third (2/3) of the report in 2 hours.**
