<PRE><B>Question 834632</B>
Notice the slow vehicle leaves first and travels for more time.  In this example, the time difference is 1 hour. The slow vehicle travels for t+1 hours of time.  The faster but later-starting vehicle travels for some t hours of time.  t is an unknown variable.  When that information is straight, then continue....


READY?


t = time for the car to meet the same distance as the traveling bus
d = the distance from LA that car and distance match


In case a table would help,


____________________speed_____________time______________distance
Bus_________________50________________t+1_______________d
Car_________________70________________t_________________d


Basic equation for uniform rates for travel, {{{highlight_green(Rate*Time=Distance)}}}


... Further process is not continued here (yet), but you try to solve the example exercise yourself, from what has been presented so far. Can you continue and finish?</PRE>
