<PRE><B>Question 175044</B>
The table shows the distance travelled buy each person for each period of time.

Time       Distance travelled
           Carlos  (starts at 8:00 AM)        Juanita
9:00 AM    50 miles (1 hour at 50 mph)        0 miles (starts at 8:00 AM)
10:00 AM   100 miles (2 hours at 50 mph)      60 miles  (1 hour at 60 mph)
11:00 AM   150 miles (3 hours at 50 mph)      120 miles (2 hours at 60 mph)
noon       200 miles (4 hrs at 50 mph)        180 miles (3 hrs at 60 mph)
1:00 PM    250 miles (5 hrs at 50 mph)        240 miles (4 hrs at 60 mph)

You continue building the table until Carlos and Juanita have traveled the same number of miles.  Note as the two cars get closer the change in time (I have used 1 hour in the table above)that you make your calculation of the distance traveled should get smaller (30 minutes, then 15 minutes, etc)

I hope that this helps.    </PRE>
