A river boat can travel at 20km per hour in still water. The boat travels 30km upstream against the current then turns around and travels the same distance back with the current. IF the total trip took 7.5 hours‚ what is the speed of the current? Solve this question algebraically. Let x = speed of current Upstream speed=20+x Downstream speed=20-x =) 30/20-x + 30/20+x = 7/5 =) (20-x)(20+x) = 400-x^2 =) 30(20-x)+30(20+x)=7.5(400-x^2) =) 600-30x+600+30x=3000-7.5x^2 =) 7.5x^2 = 3000-1200

Such an awesome party it was going to be‚ with an unlimited amount of space‚ people‚ and lack of restrictions. This was definitely going to be a trip to be remembered.
