Miley travel from home to school to work and back home again in 60 different ways
<em><u>Solution:</u></em>
<em><u>Miley walks to school by 1 of 3 routes in the morning</u></em>
So she chooses 1 route from 3 routes
Number of ways = 1 x 3 = 3 ways
<em><u>After school she chooses from 4 different routes to get to work</u></em>
So she has 4 different routes and she picks up 1
Number of ways = 1 x 4 = 4 ways
<em><u>When work is done she travels home by 1 of 5 different ways</u></em>
So she has 5 different routes and she picks up 1
Number of ways = 1 x 5 = 5 ways
<em><u>How many different routes can Miley travel from home to school to work and back home again?</u></em>
Total number of different ways = 3 ways x 4 ways x 5 ways
Total number of different ways = 3 x 4 x 5 = 60 ways
Thus Miley travel from home to school to work and back home again in 60 ways
