4,280
Reason:
Frank drives 60miles per 1 hour ( 1:60)
If he drives 120miles, its per 2hours because you multiply by 2.
If he drives 360miles, its per 6 hours
Because 60x6=360 and 1x6=6 (6:360)
4,280 is odd one out because if he drives 4hours, you multiply 60 by 4 to get 240, 280 is incorrect
I know its long but I hope it helps
