A-level electron speed question

[felix-corpus]

calculate the speed of an electon which has a de broglie wave length of 1.3x10^-10m


can anyone help me with this question I've never had one like this come up so i haven't a clue what to do, with only 2 weeks to my a-level exams

Have you come across the de Broglie relation
$$\lambda = \frac{h}{p}$$
for matter waves?
