To average 60 miles an hour, the car has to complete the 2nd loop instananeously.
Here's why the other answers are wrong. The car took 2 minutes to go around the loop at 30 mph. At 90 mph, the car would complete the second loop in 45 seconds. That makes the total travel time 2:45 for the two loops (2 miles total distance).. which is not 60 mph average.
The other answerers are incorrectly assuming the car can travel at 90 mph for 2 minutes, the same amount of time it took to complete the first loop at 30 mph. That contradicts the question, which only mentions going around the loop a "2nd time".
props to JTRaceFan who came up with the same answer as I was typing this out.

Can't be done. One must cover the two laps in 120 seconds. The first lap at 30 mph consumed the 120 seconds.

Takes two minutes for the first loop, needs to do two loops in two minutes to average 60...
Put the hammer down.

If you travel at the speed of light, time will stand still. So you will need to do about 186,000 miles per second. Be sure to wear a helmet.
