A cyclist bikes x distance at 12 miles per hour and returns over the same path at 8 miles per hour. What is the cyclist's average rate for the round trip in miles per hour?	Choose the correct choice from the following answers
A) 8.1	B) 8.3	C) 9.6	D) 8.9	E) 9.0
Distance = d1 = x miles   Speed = s1 = 12 miles per hour   Time = t1 = Distance/ Speed = x/12   2. Going from B to A   Distance = d2 = x miles   Speed = s2 = 8 miles per hour   Time = t2 = Distance/ Speed = x/8   3. Average Speed = Total Distance/Total Time   Total Distance = x + x = 2x   Total Time = x/12 + x/8 = x (1/12 + 1/8) = =5x/24   Speed = 2x/(5x/24) = 48/5=
