A compact car, mass of 725 kg, is moving at 100 km.hr. What is its momentum? At what velocity is the momentum of a larger car, mass 2175 kg, equal to that of the smaller car?

this is what i have so far:

p=725(100 km/hr)

but i don't kno how to change km/hr into m/sec. And i don't know how to do the second part of the question.

Please help!
