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)

How long should it take a 35 year old to run 1 mile?
It depends on how experienced you are as a runner. Beginner: 3 miles or so (11-12 min/mile) Average runner: about 3.5 miles (10 min/mile) Fast: about 4.5 miles (8 min/mile) Experienced XC runner: about 5 miles (7 min/mile) Elite runner/really awesome XC runner: about 6-7 miles (5-6 min/mile) Anything faster than 5 min/mile for 35 minutes is craziness. If you ran more than 7 miles in 35 minutes...you don't need to be asking whether that's a good number of miles :P
