Question

Dominic walks half a mile to school every weekday. he walks home from school on Tuesdays, Thursdays, and Fridays, but rides the bus home after activites on Mondays and Wednesdays. how many miles does Dominic walk to and from school over 18 weeks?

Answer 1

We go to school 5 days a week
Dominic walks .5miles to school every week day.
He walks home .5miles Tues, Thurs, Fri.

So first find the total number of miles he walks in the mornings for the week which is...

.5miles・5 = 2.5miles per week

Then find the miles he walks home per week which would be...

.5miles・3 = 1.5miles per week

The you find the total number of miles he walks in a week which would be...

2.5 + 1.5 = 4miles per week total

Then to find 18 weeks... all you have to do is...

4miles・18 = 72miles

He walks 72 miles overall in 18 weeks.

And if you want to find just afternoons or just mornings for 18 weeks...

Mornings
2.5miles・18 = 45miles

Afternoons
1.5miles・18 = 27miles
