PRACTICE: Write an auton routine that drives the robot forwards 10 feet

I realized I should put this in writing somewhere, so here it is. Unfortunately, there isn't a great way to drive forwards a set distance yet, just a set time. So, this task is to get that set up: figure out the time you have to drive at 0.7 speed to go forwards about 10 feet. If you find a time that's close, you can comment it on this issue; the more accurate, the better!
