A famous group bike ride in Tucson is the Shootout. It takes place every Saturday morning and attracts many pros in the winter months. Let x = f(t) models the

distance the cyclists have ridden as a function of time (where x is in miles and t is in hours). \text { If } f(1)=25 . \text { What does this represent in the context of the problem? } \text { If } f^{\prime}(1)=28 \text {. What does this represent in the context of the problem? }
