C=2*pi*r If you were to double the circumference, since the only variable in the equation is r, that means the radius is double. Since A=pi*r^2, if the radius is double the area is the square of double or quadrupled so it increases by a factor of 4
log(5^(1+x))= log(2^(1-x)) (1+x)(log 5)= (1-x)(log 2) (x+1)/(x-1)=.4306765581 x+1= .4306765581x-.4306765581 At this point it's a simple algebraic solution to solve for x. :)
If you think about it, the total distance travled in the x direction is equal to the y direction since to get the max an object can go in the x direction is acquired at a 45 degree angle. So you are going a total of 149 m, at the highest point the distance
