Marco ran from his house 2.67 miles to a county park. He then ran the 1.5 mile cross country loop at the park and back home. How many miles did Marco run altogether?

I added and got 4.17 miles

Is that correct

No. You left him at the park -- but he hasn't gotten home yet.

Do I add 2.67 and 1.5+1.5

Is my answer 1.5 miles

No.

First he ran to the park = 2.67 miles

Then he ran around the park = 1.5 miles

Finally he should run home = 2.67 miles

Look at Ms.Sue's answer and my diagram.

Do I add and is my answer 6.84

Yay! You've got it. Whew! Now Marco is back home!

His total run was 6.84 miles.

To verify if the calculation is correct, you need to add the two distances that Marco ran.

First, Marco ran from his house to the county park, which is 2.67 miles.

Then, he ran the cross country loop at the park, which is 1.5 miles.

To find the total distance Marco ran, you add these two distances together:

2.67 miles + 1.5 miles = 4.17 miles

Therefore, your calculation of 4.17 miles for the total distance Marco ran is correct.
