A careful pronunciation is roughly:
Noo zah-von zah-say duh ton
A few points:
Avons is the present tense of avoir for nous:
So Nous avons assez de temps is in the present tense: We have enough time.
Normally, this is the standard word order:
French does not usually rearrange this the way English sometimes can.
You could change it for emphasis in special contexts, but for normal use, keep this order:
subject + verb + quantity expression + noun
So this sentence is a very typical and natural structure.
