So what u need to do is
46+x=180 and u will get the answer
Once you complete the square, the simplified version of this equation is
(2x - 1)^2= 0
If you want to solve for x, subtract 1 and divide by 2.
x = 0.5
We know that: <span>3(x-1)^2-162=0
or (x-1)</span>²= 162:3
and (x-1)²= 54
we <span>take the square root of both sides
* x-1=</span>√54= 3√6 or x=1+3√6
* x-1= -<span>√54= -3√6 or x=1-3√6
This equation has 2 solutions</span>
45km : 30 min = 180km : x
x = 
= 
= 60*2 min = 120 min = 2h
