Question 128755
50X=75(X-1)
50X=75X-75
50X-75X=-75
-25X=-75
X=-75/-25
X=3 HOURS AFTER THE FIRST BUS LEFT THE FASTER BUS OVERTOOK IT.
PROOF:
50*3=75(3-1)
150=75*2
150=150

Thank you so much for your help with this.  Your reply was very quickly received.  I have a follow up question.  What is X standing for?  If I read it correctly, we first have to solve for how much time it took for the express bus to overtake the public bus, and then once we have the time, we can determine the distance?  Am I understanding correctly?
