Clark is alone in a cave and eager to leave it. Looking at his map of the cave (shown below), Clark sees that there is a special tunnel close to his current location that would take him directly back to the entrance of the cave. How much shorter would it be for Clark to take the special tunnel than for him to follow the main path out of the cave? Round your final answer to the nearest tenth of a meter. Do not round intermediate calculations. Coordinate values are in meters.
