A speaker that emits sound is located at the origin of a coordinate system. Two microphones are located on the x-axis, with microphone 1 at the x = 3.0 meter mark and microphone 2 at the x = 5.0 meter mark. If the speed of sound is 343 m/s, how much longer does it take a sound emitted by the speaker to reach microphone 2 than microphone 1?
