Nikki spends 1
4 of an hour driving to work each day and
1
2
of an hour driving home. She works every day except Saturday and Sunday.

How long does she spend travelling each week?

2 3/4 hours

Step-by-step explanation:

Since there are 7 days in a week and she doesn't work 2 of them so 7-2=5 days that she works. Then to find out how much she time she spends traveling multiply the time by the days, 1/4x5/1)+(1/2x5/1)=5/4+5/2=1 1/4+1 1/2=2 3/4
