Answer :

5 routes to go to school library
and 6 routes from the library to back home:
So she has 5 ways to be chosen & 6 ways (back home) to be chosen. then she has all in 5x6 ways = 30 ways 

Answer:

30 ways is the answer.

Step-by-step explanation:

Lets suppose Ruth Ann picked route A (one of the 5 routes) and got from the school to the library. She has 6 choices of how to get from there to her home.  

So route A combined with her 6 choices for the remaining trip is 6 routes for a complete trip.  

If she had picked a different route, say route B from the school to the library, then also she still has 6 choices of how to complete the trip.

This shows that each of her 5 choices for the first part of the trip can be completed using one of the 6 choices for the 2nd part of the trip.  

So, total routes will be 5 x 6 = 30.
