<PRE><B>Question 865222</B>
It took a mule 2/3 of an hour to go 4/5 of a mile.
 At that pace, how long would it take the mule to go 1 mile?
Let t = time (in hrs) to go 4/5 mi
Time = dist/speed
t = {{{(4/5)/(2/3)}}}
invert the dividing fraction and multiply
t = {{{4/5}}} * {{{3/2}}} = {{{12/10}}} = 1.2 hrs
:
 How far would the mule go in an hour
Change 4/5 to .8 mi
{{{.8/1.2}}} = {{{2/3}}} mi in 1 hr  </PRE>
