a rock is thrown down from the top of a 500-foot cliff. After 1 second, the rock is traveling 47 feet per second. After second the rock ia traveling 111 feet per second. Assume that the relationship between time,t, and speed,s, is linear and write an equation describing this relationship. Use ordered pairs of the form (time,speed).
