We can have two d = rt equations.

d = 40 t

d = 50 (9 - t)

We know the distance is the same, so we can just set the equations equal to each now.

40 t = 50 (9 - t)

40 t = 450 - 50 t

90 t = 450

t = 5

So, Terrell took 5 hours going 40 mph, and 4 hours going 50 mph. 5 * 40 gives us 200 miles one way.

makkiz [27]
Hello :
<span>note : 
 an equation of the circle Center at the w(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²  
in this exercice : </span><span>x²+y²-16x+6y+53=0
(</span>x²-16x) +( y²+6y ) +53 = 0
(x² -2(8)x +8² -  8²) +(y² +2(3)x -3²+3² ) +53=0
(x² -2(8)x +8²) -  8² +(y² +2(3)x +3²)-3²  +53=0
(x-8)² +( y+3)² = 20 

the center is :  w(8,-3) and ridus : r  = <span>√20</span>
