Okay. First, think about what conditions mean that one car passes another...

I don't understand?

well their distance travelled after the landmark must be same right?

Yes

I don't know how to do that. D:

I'm sorry, I really don't understand this. I need help.

Refer to the attachment from Mathematica.

|dw:1440487713058:dw|

following?

Yes sir/ma'am

Then, distance=speed*time, right?
That would mean 55*t=63*(t-1)

solve this for t!

7.875?

yeah, sorry but the question need t-1 right?

I chose t to be time elapsed for first... so 6.875 will be the answer.

shouldn't it be `t+1` since it was an hour later?

`t-1` would mean the second car left an hour before the first, no?

t represents time elapsed after crossing the landmark.

Let t be the time to catch the first car.
55 (1 + t) = 63 t // Solve
t = 55/8 = 6.875

Thank you for the medal.
