house. How many miles from his house was Cole
after he finished hiking the third trail?

Answer 1

It took 9.7 miles away from his house after he finished hiking the third trail.

Explanation:

Given:

Cole went hiking near his house.

The first trail took him 12 miles away from his house.

The second trail took him 5.2 miles closer to his house.

The third trail took him 2.9 miles further away from his house.

Now, to find the distance of miles Cole was away from his house after he finished hiking the third trail.

So, we the first trail took him away but second took him closer so we subtract the second trai from the first:

`12\ miles -5.2\ miles=6.8\ miles.`

Now, the third trail took him further away so we add then :

`6.8\ miles+2.9\ miles=9.7\ miles.`

Therefore, it took 9.7 miles away from his house after he finished hiking the third trail.
