Let the time that it takes Scully to catch up with Mulder be T

Then time it'll take Mulder to get to catch-up point = T + 30 minutes, or T+%2B+30%2F60 hour, or T+%2B+1%2F2

Create a DISTANCE equation, since Scully's distance, equals Mulder's distance. Since D = ST (distance = speed * time), this translates to:

68T+=+65%28T+%2B+1%2F2%29

68T+=+65T+%2B+65%2F2

136T+=+130T+%2B+65 ------ Multiplying by LCD, 2

Solve for T and this should give you the time that it'll take Sculler to catch up with Mulder. Add this to 9:00 AM to determine the ACTUAL TIME Sculler catches up to Mulder.

You then do a check!!
