- Suppose you drop a rock into a dark well and, using precision equipment, you measure the time for the sound of a splash to return. (a) Neglecting the time required for sound to travel up the well, calculate the distance (in m) to the water if the sound returns in 2.1500 s. m (b) Now calculate the distance (in m) taking into account the time for sound to travel up the well. The speed of sound is 338.30 m/s in this well. mA cop spots a car speeding at 106 mph and immediately starts after the perpetrator.

What was the average speed of the runner in m/s? I understand that I would have to divide the total distance by the total time, but I'm not sure how they changed the miles to meters. Please detalied steps of how to solve this so I can understand it. Thank you!
