<span>5x^2 + 5y^2 + 10x − y = 0 it is the same of </span>
<span>x^2 + y^2 + 2x −1/5y = 0
and then </span>
(x + 1)^2 - 1+ (<span><span>y−1/10)^2 -1/100=0
</span> </span>(x + 1)^2 + (<span>y −1/10)^2 =(101/100)
the center is C(-1, 1/10), and the radius is R= sqrt(101)/10

Speed = Distance / Time
SI unit for Distance is meters, m, and for time is seconds, s,
Speed = Distance / Time = m/s
Option b.
I'm pretty sure it's y divided by 5 because the fraction bar means divided by
6000 x 10% x 5
=600x5
=3000
