Set up: One (1) mile circumference race track; one operational motor vehicle and one driver.

1st lap: Driver travels one lap around the track and averages 30 miles per hour.

2nd lap: How fast does the driver have to drive the second lap to average 60 mph for the 2 miles?

p.s my NASCAR friends hate me.

He can't.  The first lap used up his 2 minutes necessary to average 60 overall.  He would have to run the second lap at infinite speed
