He's already used up all of his time if he went only 30 mph in the first lap. He needs to cover 2 miles in 2 minutes. He took 2 minutes for the first mile so he didn't qualify

Correct. He can not make it. You would be amazed at how many people insist that 90mph will get it done and will not accept the real answer.
