Why was it better to measure distance rather than time to  determine reaction time?

Reaction times can be measured by a variety of techniques in the lab. the simplest test is to present a stimulus to a test subject and instruct the subject to press a button as fast as possible after the stimulus is perceived. responses can be measured by using a response box.
