First convert this into improper fraction so that -3 2/3= -11/3 and -4 1/2= -9/2
not multiply the numerators so you should get 99/6 or 33/2(the negatives cancel out)
<span>A motorboat takes 3 hours to travel 144 mi going upstream. The return trip takes 2 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
----------------
144/3 = 48 mph upstream
</span><span>144/2 = 72 mph downstream
The boat's speed is the average = 60 mph
The current is the difference = 72-60 = 12 mph</span><span>
