Question 1189837
<font color=black size=3>
Given info:<table border = "1" cellpadding = "5"><tr><td>Person</td><td>They <u>think</u> their clock is...</td><td>Their clock is actually...</td></tr><tr><td>Alice</td><td>8 minutes fast</td><td>3 minutes slow</td></tr><tr><td>Barney</td><td>9 minutes slow</td><td>6 minutes fast</td></tr><tr><td>Clive</td><td>3 minutes fast</td><td>4 minutes slow</td></tr><tr><td>Dolores</td><td>3 minutes slow</td><td>22 minutes fast</td></tr><tr><td>Elisha</td><td>7 minutes fast</td><td>7 minutes slow</td></tr></table>Let's say hypothetically that when each person is setting their watch, the official time is 3:00 PM.


Now let's consider Alice. Her clock is actually 3 minutes slow. Her clock displays 2:57 PM (which is 3 minutes shy of 3:00 PM). Alice thinks her clock is 8 minutes fast. 
To counterbalance things, she'll subtract 8 minutes from the clock's display to get 2:49 PM.
Alice sets her watch to 2:49 PM when the true time is 3:00 PM.


Notice the gap from 2:49 (what Alice thinks the time should be) and 3:00 (what the time is officially) is exactly 11 minutes.
Furthermore, notice that 3+8 = 11. 


In other words, Alice clock is 3 min slow and she mistakenly slows it down another 8 min to have it be 11 min slow overall.


Barney has his clock 6 minutes fast and he thinks its 9 minutes slow. Therefore, he'll add 9 to the time on his clock to be 6+9 = 15 minutes fast.


The other clocks are adjusted in a similar fashion


After such adjustments, we have this<table border = "1" cellpadding = "5"><tr><td>Person</td><td>His or her watch is...</td></tr><tr><td>Alice</td><td>11 minutes slow</td></tr><tr><td>Barney</td><td>15 minutes fast</td></tr><tr><td>Clive</td><td>7 minutes slow</td></tr><tr><td>Dolores</td><td>25 minutes fast</td></tr><tr><td><font color=red>Elisha</font></td><td><font color=red>14 minutes slow</font></td></tr></table>The person with the slowest watch will arrive at the restaurant last. That table shows that <font color=red>Elisha</font> is the unfortunate one to draw the shortest straw here.


If you're curious about each person's arrival time (the true time, not what their watch says), then we would have this<table border = "1" cellpadding = "5"><tr><td>Person</td><td>When they *actually* arrive at the restaurant</td><td>Notes</td></tr><tr><td>Alice</td><td>6:11 PM</td><td>11 minutes after the true time of 6:00 PM</td></tr><tr><td>Barney</td><td>5:45 PM</td><td>15 minutes before the true time of 6:00 PM</td></tr><tr><td>Clive</td><td>6:07 PM</td><td>7 minutes after the true time of 6:00 PM</td></tr><tr><td>Dolores</td><td>5:35 PM</td><td>25 minutes before the true time of 6:00 PM</td></tr><tr><td><font color=red>Elisha</font></td><td><font color=red>6:14 PM</font></td><td>14 minutes after the true time of 6:00 PM</td></tr></table>This table helps further show that <font color=red>Elisha</font> is the last to arrive.
