Answer by ptaylor(2198) (Show Source): You can put this solution on YOUR website!
Distance(d) equals Rate(r) times Time(t)or d=rt; r=d/t and t=d/r
Let t=time it takes 'till they meet
Distance Bob drives=50t
Distance Bill drives =60t
Now when the above two distances add up to 450 miles, they will have met, so:
50t+60t=450 collect like terms
110t=450 divide each side by 110
t=4.1 hr----------------------------time it takes them to meet
CK
50*4.1+60*4.1=450
204.5+245.5=450
~~~450=450
