Answer 1

Answer:

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

Step-by-step 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.
