The key is to find out how much of a head start the
accountant has. He gets a 1 hour head start at 50 mi/hr
mi is his head start
Now start a stopwatch when his boss leaves, and call
the time when they meet at the station.
Let = the distance the boss has to travel
will be the distance the accountant has to travel
-------------
For the accountant:
(1)
For the boss:
(2)
-------------
Substitute (1) into (2)
(2)
hrs
Plug this back into (2)
(2)
This is the entire distance that the boss has to travel,
so the towns are 300 miles apart
check answer:
The accountant goes miles in
(1)
hrs
OK
