Let http://edugen.wileyplus.com/edugen/s...=1343834891985 be the position function of a particle moving along a coordinate line, where *s* is in feet and *t* is in seconds.

Find the maximum speed of the particle during the time interval http://edugen.wileyplus.com/edugen/s...=1343834891985

The maximum speed is ft/s.
