We all like to take our Rovers on a long trip every now and then, so calculating our average speed for the trip might be something we might like to do on occassions.
So here is a little question to ponder and to post your answers to.
A driver sets out on a journey. For the first half of the distance she drives at a leisurely pace of 60km/h; she drives the second half at 120km/h. What is her avergae speed for the trip?
