Question 31292: ching leaves san fran. and travels toward la. at 50 mi/h. and hour later phil leaves la. and travels toward san fran. at 60mi/h. if the two cities are 380 miles apart, how many hours will it take for ching to meet phil? Answer by Paul(988) (Show Source):
You can put this solution on YOUR website! Let the time be x
Equaiton:
50(x+1)+60(x)=380
50x+60x=380-50
110x=330
x=3
3+1=4
Hence, it will take him 4 hours to meet him.
Paul.
