alright, so I was testing with one of my little brothers how fast I could move. We were just goofing around. He decided for the final test to enter the bathroom, and wait behind the door. He held the door about 1-2 inches away from being closed, and I had to run and try to open the door before he closes it. I was approximately 5 ft 5 inches away from the door, while he held the door literally 2 inches from closing. I told him to go for it when I begin moving. I immediately moved forward and straight up kicked the door open (he hadn't even closed it) on him. I checked how fast I moved. I moved 5 and a half feet, in literally 1-2 seconds. I basically ran up to the door, and opened it further with a kick in about 1-2 seconds.
