A swimming pool is open for 7\dfrac127 2 1 7, start fraction, 1, divided by, 2, end fraction hours during a day. The pool keeps one lifeguard on duty at a time, and each lifeguard's shift is 1\dfrac121 2 1 1, start fraction, 1, divided by, 2, end fraction hours long. How many shifts are there per day?

5 shifts

Step-by-step explanation:

The pool is open for 7 1/2 hours (15/2 hours) per day.

Each lifeguard shift lasts for 1 1/2 hours (3/2 hours).

To get the number of shifts per day, we divide the total hours that the pool is open by the time of each lifeguard shift:

There are 5 lifeguard shifts per day.
