A small motorboat travels 12 mph in still water. It takes 2 hours longer to travel 66 miles going upstream than it does going downstream. Find the rate of the current. Round your answer to the tenth.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

using pemdas, (order of operations) you'll see the answer is 24.
