Answer:
2/13,140
4/105,120
6/40,832
8/35,100 or 6/23,400
Step-by-step explanation:
Cala's car is 2 years old, drives 18 miles per day times 365 days in a year times 2 years old is 13,140 miles in 2 years.
Lara's car is 4 years old, drives 72 miles a day times 365 days in a year times 4 years old is 105,120 in 4 years.
Jamal's car is 6 years old, drives 64 miles per day times 365 days a year times plus 56 miles a week times 52 weeks in a year times 6 years old is 40,832 in 6 years.
Ali's car was 2 years old when he got it 6 years ago. His car is 8 years old and he drives 15 miles per day times 52 weeks in a year for 5 days each week, times 6 years is 23,400miles in 6 years. If you average what he drives per year and add that to 23,400, the car has approximately 35100 miles in 8 years.
