1200 is the correct answer
X is 30 because we can minus 60on both sides and add 3x on both sides to find the answer
<span>y-(-2)=3/5*(x-10)
This can be simplified to y+2=3/5*(x-10)
In slope y-intercept form the equation is
y=3/5*x-3/5*10-2= 3/5x-6-2= 3/5x-8
y=(3/5)*x-8</span>
3/4 of an hour = 45 minutes
45 * 3 = 135 minutes
135 + 45 = 180 minutes
He spends 180 minutes or 3 hours
