If you drive one mile at 30 mph how fast do you have to drive the second mile if you have to average 60 mph for the two miles?

Yes, you can. If the average speed for the first mile is 30 mph, and the average speed for the second mile is 90 mph, then 30+90=120/2=60. You need to solve the equation for average speed, not time.
You can't.
1 mile @ 30mph = 2 minutes
60 mph for 2 miles = 2 mintes
thererfore you cannot go fast enough
(or you could go infinity mph)
