Let speed of boat is x km/hr: speed of stream is y km/hr downstream = x+y upstream = x-y therefore equation will be 30/x-y + 28/x+y =7 21/x-y + 21/x+y =5 let x-y= 1/p and x+y= 1/q 30p + 28q = 7 multiply 1 by 3 90p+84q=21 21p...

(a^2-bc)^2=(c^2-ab)(b^2-ac) a(a^3-2abc)=a(-b^3-c^3+abc) a=0(or)a^3+b^3+c^3=3abc
