Question

Jenny is on the local swim team for the summer and has swim practice four days per week. The schedule is the same each day. The team swims in the morning and then again for 2 hours in the evening. If she swims 12 hours per week, how long does she swim each morning?​

Answer 1

1 hour each morning

Explanation:

The question says that Jenny practices 4 days a week, and swims 2 hours in the evening, while also swimming in the morning on those days. She swims 12 hours per week, so if we are trying to find how long she swims each morning, we have to stick with what we know first. To get started, we should multiply 4 by 2, because she swims 4 days a week for 2 hours in the evening. To find what amount she swims during the evening, we have to multiply:

4 * 2 = 8

Now we know she swims 8 hours in the evening. All we have to do now is subtract the total amount of hours swam (12) by 8, which comes out to:

12 - 8 = 4

So Jenny swims for 4 hours in the morning each week, and since she swims 4 days in a week, we divide:

4 / 4 = 1

So Jenny swims 1 hour in the morning

Answer 2

1 hour each morning

Explanation:

4 times a week

2 hours in afternoon

12 hours per week

4x2=8

12-8=4

4 divided by 4 = 1

Check my work:

1 hour each morning

total of 3 hours a day

4x3=12
