A person drives from A to B to get to work at a constant speed of 30 km/hr. They were running a little late for a hot date, so they decided to rush a little bit on the way home. If the average speed the person traveled over the round trip form A to B and B to A was 55 km/hr, how fast were they traveling on the way home?
Ok. I got the formula slightly wrong, but I have amended it and arrived at an answer.
I can only hope there were no police about when he was driving home!!
