Can anyone please help me with this question? I don't understand why the speed is v m/s.

A sport utility vehicle is travelling at a speed of v m/s. If its momentum has a magnitude of 32,800 kg·m/s, what is the SUV's mass?

Thanks
I know that I have to use the formula
p= m*v and then m=p/v, but what is the value of the speed?
