Question

3. Paula commutes 60 km each day for work, five days a week, nine months of the year. She travels 720

km four times a year to visit family members. She also drives another 200 km/month.
a) About how many kilometres does Paula drive in one year? Assume there are four weeks in each
month.

Answer 1

16,080 km.

Explanation:

We want the total number of kilometers in one year.

so

4 weeks /month.

for Work: 9 months in the year 60 km/day 5 days/week

Family Visit : 720 km for 4 times a year

Personal: 200 km / month

Work total = 60 km/day * 5 days/week * 4week/month * 9 months

WorkTotal= 60*5*4*9 = 10,800 km

FamilyTotal= 4*720 = 2880 km

Personal = 200*12 = 2400 km

Total = 10,800 + 2880 + 2400 = 16,080 km
