If Zack has basketball practice in 2 hours, the angle measure of the clock hands could be 120 degrees. This is because the minute hand will move 30 degrees every hour, so in 2 hours it will move 60 degrees. Starting at 150 degrees, if the minute hand moves 60 degrees, it will end up at 210 degrees (150 + 60 = 210). However, the hour hand will also move slightly, typically moving 1/2 a degree for every minute that passes. This means that it will move 120 degrees in 2 hours (60 minutes in an hour x 2 hours x 1/2 degree = 120 degrees). So, the angle between the hour hand and minute hand will be 210 degrees - 120 degrees = 90 degrees.
