Rate*Time=Distance.
R%2At=D
During the two hours, the first car travels,
D=55%2A2=110 miles.
The distance from the starting point for the first car is then,
D%5B1%5D=110%2B55%2At
The distance from the starting point for the second car is,
D%5B2%5D=60%2At
Find t when D%5B1%5D=D%5B2%5D
110%2B55t=60t
5t=110
highlight%28t=22%29hrs
