ok got it now
basically in second 6 = combined time so in one hour they'll do 1/6 work
1/t + 1/2t = 1/6, then both sides are multiplied by 6 to simplify.
remember formula
1/x + 1/y = 1/k where x=time for first person alone , y = time for second person alone and k=time for both
hope its clear now.

2> is already discussed anyway xy + z = xy + xz => z = xz so z = 0 or x = 1 3> I'm getting value in between 1/2 and 1 not sure if question is typed correctly, basically you'll get a sequence of -1 + 1/2 + 1 + 1/4 - 1 + 1/8.... -1 and 1 will cancel out leaving 1/2 + 1/4 +...+1/32 so that should be mo...

IMO C, for any x>=0.75 and y>=0.75 equation is satisfied, the square has side of length 2 so area will be 4, so considering given options I considered a circle with center (0,0) and radius 1. any point out of this circle (area = pi * r^2, here r=1) will satisfy the equation
hence 4 - pi

for second say x = walking speed and y be riding speed and d be one side distance d = s * t so d/x + d/y = 50 minutes (I) 2d/x=70 so d/x = 35 putting in first d/y + 35 = 50 so one side d/y = 15 which is one side ride hence 30minutes for both ways in 3rd 20km is covered in 15 minutes so 80km/hr is th...
