A car is at position $(x_1,y_1)=(4m,5m)$ at time $t_1=1s.$ If $10$ seconds later the car moving in a straight line is at position $(x_2,y_2)=(204m,305m),$ calculate the magnitude of the average velocity during this interval.

$36\mathrm{.}1$ m$/$s

$32\mathrm{.}8$ m$/$s

$36\mathrm{.}7\frac{m}{s}$

$50\mathrm{.}0\frac{m}{s}$

$40\mathrm{.}1$ m$/$s
