At time t, in hours, a lake is covered with ice of thickness y cm, where y = 0.3t¹.7. 1. How fast is the ice forming when t = 1? When t = 2? Give units. when t = 1: when t = 2: 2. If ice forms for 0 ≤ t ≤ 3, at what time in this interval is the ice thickest? At what time is the ice forming fastest? (Give units here, too.) Ice is thickest at t = Ice is forming fastest at t =
