The following equation represents the average rate for the trip. Is this equation equivalent to the one you wrote above? Explain why or why not. 12 2 Average Rate = + d dd rrd) The following steps show how the equation for the average rate can be transformed so that it is written in terms of only the rates for each leg of the trip. Write an algebraic justification for each step. Think about the number operations and properties that you know. 12 2 Average Rate = + d dd rr2 1 1 2 1 2 1 2 1 2 22 Average Rate = = + + dd rd rd rd rd rr rr rr12 12 12 1 2 1 2 12 222 Average Rate 1 = =  = +++
