Write a program that takes as input from the user distance $x($in $m)$ and time $t($in s$)$ and computes the speed

$v=\frac{x}{t}.$

and outputs the speed in $(1)$ units of $\frac{m}{s}$ and $(2)$ units of $k\frac{m}{h}.$

The output of your program should be $($for $x=8\mathrm{.}4m$ and $t=2s)$:

$dx(m)$:$8\mathrm{.}40$

$dt(s)$:$2\mathrm{.}00$

speed $(\frac{m}{s})$:$4\mathrm{.}20$

speed $(k\frac{m}{h})$:$15\mathrm{.}12$

Use. format $()$ to print floating point numbers to two decimal digits as in the example above.
