Find a max possible value of an undefined function in an interval when derivative is a constant [closed]

The function $$f(x)$$ is continuous and differentiable in $$[0,1]$$ if $$f'(x)\le 10$$ for all $$x\in[0,1]$$ and $$f(0)=0$$,

What is the maximum possible value of $$f(x)$$ for $$x\in [0,1]$$ ?

Any help would be greatly appreciated, thanks.

$$\forall x\in [0,1]$$ we have,
$$\frac{f(x)-f(0)}{x-0}\le 10$$ {By lagrange's mean value theorem we have a $$c\in [0,x]\ such\ that\ \frac{f(x)-f(0)}{x-0}=f'(c)\le10$$}
$$\therefore$$ maximum value of f(x) is 10$$x$$ in [0,1].
