Friendship Sum

Two room mates meet on craigslist. One's a bus driver, moir-is a college dropout living on retirement.

The persons--share a room, 4x4, 500sqft. What is the sum total of each equal sides? If you get by this point, they've gotten nowhere. They need your help. What's the sum of 10^2 mirror, respectively? Sum:

They both need your help: They were lying to each other, funny thing, one is a stand-up comedian, posing as a bus-driver, and the other one posing as a loser, but an aspiring Comedian also.

Saudimir Ghandi weighs 225lbs. Thomas Vishnu weighs 150lbs. After they both weigh in at the dentist (for some odd reason), they noticed that they should probably both lose 20% body mass. They both drink 2 gallons of water and run 10 miles.

Ghandi burns his fat and loses 1lbs for every mile. Vishnu with respect loses the same.

How many miles does Ghandi need to run?

How many miles does Vishnu need to run?

What is the sum total of their expected weight (noting that temperature, what they eat, etc...) don't play a factor?

Hint: If it's an odd number, they will hug, otherwise they'll keep eating more and get heavier again, zero-sum-gain.
