Rachel and two friends signed up for membership in a fitness club. One friend spent 3 hours per week at the gym for the full year, and another friend averaged 2 hours per week for the year. Rachel spent 4 hours per week for 16 weeks, then stopped.

How many total hours did the friends spend in the gym?

1. 220
2. 260
3. 324
4. 364
5. 468​

Answer :

To calculate the total number of hours spent by Rachel and her two friends in the gym, we need to add up the hours individually.

Friend 1 spent 3 hours per week for the full year:

3 hours/week * 52 weeks = 156 hours

Friend 2 average 2 hours per week for the year:

2 hours/week * 52 weeks = 104 hours

Rachel spent 4 hours per week for 16 weeks:

4 hours/week * 16 weeks = 64 hours

Now, we can calculate the total hours spent by all three friends:

156 hours + 104 hours + 64 hours = 324 hours

Therefore, the three friends spent a total of 324 hours in the gym.

The correct answer is (3) 324.
