At rider's heigh, $h,$ in metres on a Ferris wheel can be modelled by the equation Where $t$ is the amount of time that has passed in seconds.

$h(t)=16sin(\frac{2t}{48})+17$

Calculate the average rate of change in the rider's height between $38$ and $48$ seconds. Round to one decimal.

a$)1\mathrm{.}5\frac{m}{s}$

b$)0\mathrm{.}3\frac{m}{s}$

c$)-2\mathrm{.}4\frac{m}{s}$
