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,

... 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?
