To check the velocity of flow through a stretch of sewer, a collection system operator dropped a float into the flow at the manhole where she stood. When she dropped the float, a coworker at the next downstream manhole started a stopwatch. The two manholes are 386 feet apart. It took 2 minutes and 56 seconds for the float to reach the coworker. Calculate the velocity of the flow in the sewer in feet per second.
