Mr. Hernandez runs his car at a regular speed of 50kph and Mr. Reyes at 36kph. They started the same time at 5:30 AM and took opposite directions. At what time will they be 600 km apart?
--------------
Hernandez DATA;
Rate = 50 kph; Time = x hrs; Distance = rt = 50x km
----------------
Reyes DATA:
Rate = 36 kph; Time = x hrs; Distance = rt = 36x km
-----------------
EQUATION:
distance + distance = 600 km
50x + 36x = 600
86x = 600
x = 6.98 hrs
Note: 0.98 hrs = 58.8 minutes
--------------------
5:30 + 6 hr 58.8 minutes is approximately 12:30 PM
