Answer 1

At 97.5-mile mark.

Explanation:

A 225- mile bike ride relay had 5 sections. Marlene rode the 75 to 120-mile section.

Now, water stops were located at the halfway point of each section.

So, the water stop will be located at the midpoint of 75 to 120 miles section.

Therefore, Marlene can expect to see a water stop on her portion of the race at
`[75 + (120 - 75)/(2)] = 97.5` miles mark. (Answer)
