Lisa lives 7 miles from school. she bikes to school and back every day. how many miles does she bike in 1 school week

70

Step-by-step explanation:

You do 14*5 because she bikes 7 miles to school and 7 miles back, then a school week is 5 days

Lisa drives 70 miles in 1 school week

Step-by-step explanation:

Lisa rides her bike 14 miles in total a day since it takes her 7 miles to school and back to home. If she continues riding her bike to school each day and back for 1 school week, she would drive 70 miles in total. Since there are 5 days in a school week you multiply 14 by 5 and get answer 70. Or in other words:

1 day: 14

2 day: 14

3 day: 14

4 day: 14

5 day:  14

total: 70
