<PRE><B>Question 56906</B>
Ching leaves San Francisco and travels toward Los Angeles at 50 mi/h. An hour later, Phil leaves Los Angeles and travels toward San Francisco at 60 mi/h. If the two cities are 380 miles apart, how many hours will it take for Ching to meet Phil?

-----------
Ching DATA:
rate= 50 mph  ; Time = x hr. ; Distance = 50x mi
----------
Phil DATA:
rate = 60 mph ; Time = x-1 hr ; Distance = 60(x-1)=60x-60 mi
-------------
EQUATION:
distance + distance = 380 mi.
50x+60x-60=380
110x=440
x=4 hrs.
They will meet 4 hrs after Ching leaaves home.
Cheers,
Stan H.
