mathmale · Answer

How far is it from the house to the store, in yards?
How far would ONE round trip to the store be?
How far would THREE round trips to the store be?

mathstudent55 · Answer

Yes.
You already know that the distance from the house to the store is 1760 yards, right?

calculusxy · Answer

Yes

mathstudent55 · Answer

One round trip means two times the distance from the house to the store. OK?

calculusxy · Answer

Just to make sure was it 110,880 yards. I am kind of confused for this reason.

mathstudent55 · Answer

How did you get that number?

calculusxy · Answer

3*7=21
5280*21=110,880 yards.

mathstudent55 · Answer

Why multiply by 7?
3 trips to the store and back means 6 trips from the house to the store.

calculusxy · Answer

Okay I got that. my main question is that why would there be in one week? the problem says the phrase "one week" in there.

mathstudent55 · Answer

1 trip from the house to the store:               5280 yd 
1 trip to the store and back:                        2 * 5280 yd 
3trips from the house to the store and back: 3 * 2 * 5280 yd

mathstudent55 · Answer

The fact it's in one week makes no difference.

mathstudent55 · Answer

The only thing that matters is that it's 3 round trips to the store.

calculusxy · Answer
