Question 165578
Distance(d) equals Rate(r) times Time(t) or d=rt;  r=d/t and t=d/r

Let t=time it takes bus and train to arrive at the town after bus starts
Distance train travels=50*2+50t (Note: train already has a 2 hour head start)
Distance bus travels=60t

When the above two distances are equal they will have arrived at the town, so:

100+50t=60t  subtract 50t from each side
100+50t-50t=60t-50t  collect like terms
100=10t  divide each side by 10
t=10 hours-------------------------time it takes the bus and train to arrive after bus starts
d=rt; d=60*10=600 mi--------distance to town

CK
100+50*10=60*10
100+500=600
600=600


Hope this helps---ptaylor
