A sled accelerates down a hill and then slows down after it reaches a flat portion of ground. The speed of the sled s (t) (in ft/sec) at a time t (in sec) a movement begins can be approximated by: s(t) 1.5t 60 t - 29 for 0≤t≤30 for 30 <180 Determine the speed of the sled after 20 sec, 30 sec, 60 sec, and 80 sec. Round to I decimal place if necessary.
