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?

How much time does Kyle spend running and weightlifting? ** Half of the 2-hour practice is for running and weightlifting, so the time for running and weight lifting is 1/2 * 2 hours = <<2*1/2=1>>1 hour.
How much time does Kyle spend running? ** If the time he lifts weights is x, then the time he runs is 2x.
How much time does Kyle spend running and weightlifting? ** So the time for running and weight lifting is x + 2x = 3x = 1 hour
How many minutes does Kyle spend running and weightlifting? ** Thus 3x = 60 minutes
How many minutes does Kyle spend lifting weights? ** Thus x = 60/3 = <<60/3=20>>20 minutes spent weight lifting.
