If a man travels f miles an hour for h hours and r miles an hour for s hours, what is his average rate in miles per hour for the entire distance traveled? Choices
A) fh + rs  B) (fh + rs)/2  C) h/f + s/r  D) (fh + rs)/(h - s)  E) (fh + rs)/(h + s)
Average Speed = Total Distance /Total Time Taken   Total Distance travelled in t hours = fh   Total Distance travelled in s hours = rs   Total Time taken = h+s   Therefore , Average Speed = (fh+hs)/(h+s)   Answer (fh + rs)/(h + s)
