You need to show some effort to get help here. If you are completely stuck, I suggest you start by looking up the definition of speed.

 

[target]

t stands for time in seconds
x and y stand for distances

so to calculate the speed you need get the derrivative equations of f(t,x) and f(t,y)
then you will be able to find the speed in both the x and y directions and use the pythagoras theorem to find the speed of the object.
