Question 1001277: Hi, I'm having trouble with a word problem. Here it is: Seth climbed a mile high hill at a rate of 6 miles per hour. He descended that hill at a rate of 12 miles per hour. What was his average speed?
You can put this solution on YOUR website! Average speed is total distance divided by total time.
If the hill was one mile distant, then it took him 1/6 hour on the way up, and 1/12 hour on the way down.
Speed = Total distance/Total time
Speed = (2 miles)/(1/6 + 1/12) = 2/(1/4) = 8 miles per hour
and not what you'd expect...
