An elephant herd was moving at the rate of 6 miles per hour, 1 felt threatened, so it started running at the rate of 10 miles per hour and caught up in 5 minutes

the one elephant that felt threatened the herd had gotten a little ways in front of him there for when he started running 10 miles per hour instead of the six that the other elephants were walking he caught up by doing four miles per hour more then the other elephants were going at the time
