conversations.value: Can you walk me through the solution of: Kyle goes to basketball practice every day for 2 hours. At practice he spends half of the time shooting and the rest of the time running and weight lifting. If he runs for twice the time he spends weightlifting, how much time in minutes does he spend lifting weight?

conversations.value: Half of the 2-hour practice is for running and weightlifting, so the time for running and weight lifting is 1/2 * 2 hours = 1 hour.
  If the time he lifts weights is x, then the time he runs is 2x.
  So the time for running and weight lifting is x + 2x = 3x = 1 hour
  Thus 3x = 60 minutes
  Thus x = 60/3 = 20 minutes spent weight lifting.
