Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 70 mph and the o

uranmaximum [27]

Let

x--------> the time in hours

y-------> the distance in miles

we know that

The speed is equal to

$Speed=\frac{distance}{time}$

in this problem

$Speed=\frac{y}{x}$

$y=(Speed)*x$

Equation First Train

$y1=70x$

Equation Second Train

$y2=80x$

$y1+y2=600\ miles$ ---------> equation $1$

Substitute the values of $y1$ and $y2$ in the equation $1$

$70x+80x=600$

Solve for x

$150x=600$

$x=4\ hours$

therefore

the answer is

$4\ hours$

The sum of the areas of two circles is 8pie square meters. Find the length of a radius of each circle ifone of them is twice as

NeX [460]

Nice

area=pir^2
the areas are
pir^2+pi(2r)^2
they add to 8pi

8pi=pir^2+pi(2r)^2
undistribute pi
8pi=pi(r^2+(2r)^2)
divide both sides by pi
8=r^2+(2r)^2
expand
8=r^2+4r^2
add
8=5r^2
divide by 5
8/5=r^2
sqrt both sides
√(8/5)=r
double since it is double
2√(8/5) is radius of bigger aka (4√10)/5

radius=(4√10)/5
