Question 1060060

A boat travels 6 miles upstream in 3 hours.  Going downstream, it can travel 24 miles in the same amount of time.  Find the speed of the current and the speed of the boat in still water 
<pre>Average speed upstream: {{{matrix(1,4, 6/3, or, 2, hours)}}}
Average speed downstream: {{{matrix(1,4, 24/3, or, 8, hours)}}}
S - C = 2 ------ eq (i)
S + C = 8 ------ eq (ii)
2S = 10 -------- Adding eqs (ii) & (i)
S, or speed in still water = {{{highlight_green(matrix(1,4, 10/2, or, 5, mph))}}}
Nothing complex....very easy!!
