Answer 1

Maria has a 45-minute lunch break. She plans to do the following activities:

1. Walk 5 minutes to another floor.
2. Say "hello" to 5 different friends.
3. Spend equal time with each friend.
4. Take 5 minutes to walk back to her desk.

Let "x" be the time she can spend with each friend.

She needs to distribute her time among the 5 friends, so the total time spent should equal 45 minutes:

5x (time spent with each friend) + 5 (time for walking to the other floor) + 5 (time for walking back) = 45

Now, solve for "x":

5x + 5 + 5 = 45

5x + 10 = 45

5x = 45 - 10

5x = 35

Now, divide both sides by 5 to find the time she can spend with each friend:

x = 35 / 5

x = 7

Maria can spend 7 minutes with each friend during her lunch break.
