Laura’s House is a 20-mile round trip from her school. The supermarket is 10 miles farther away from the school. If Laura drives to school every morning and two afternoons a week drives to the supermarket. How many miles does Laura driver per week?
7 days a week Laura drives 20 miles to school, so Laura drives 7 x 20 = <T>multiply(7, 20)=140 miles to school in one week.
The supermarket is 10 miles farther away than the school. Therefore the supermarket is 10 + 10 = <T>add(10, 10)=20 miles away from Laura’s house
Laura drives 20 miles each way to and from the supermarket. Each trip is 20 x 2 = <T>multiply(20, 2)=40 miles.
Laura drives 40 miles twice a week to visit the supermarket. Therefore she drives 40 x 2 =<T>multiply(40, 2)=80 miles in total a week to and from the supermarket.
In total Laura drives 140 + 80 = <T>add(140, 80)=220 miles each week.
