Question

Javier's swim practice is 1 1/2 hours long. The team spends 1/6 of an hour stretching before they start their practice sets. If each practice set takes 1/3 of an hour, how many sets can Javier do before practice is over?

a) 3 sets
b) 4 sets
c) 2 sets
d) 5 sets

Answer 1

After subtracting the stretching time from Javier's total practice time, he has 1.3333 hours available. Each practice set takes 1/3 of an hour, and by dividing the available time by the set duration, we find that Javier can complete 4 practice sets before the end of practice.

Step-by-step explanation:

The question asks how many practice sets Javier can do before his swim practice is over. First, we need to calculate the total practice time available after stretching. Javier's swim practice is 1 1/2 hours or 1.5 hours long, and the team spends 1/6 of an hour, which is 0.1667 hours, stretching. Subtracting the stretching time from the total practice time gives us 1.5 hours - 0.1667 hours = 1.3333 hours available for practice sets.

Each practice set takes 1/3 of an hour, or approximately 0.3333 hours. Now, we divide the available practice time by the duration of each practice set: 1.3333 hours ÷ 0.3333 hours/set = 4 sets. Hence, Javier can complete 4 practice sets before practice is over.

The correct answer is (b) 4 sets.
