"How much time do you have?"

Translation: Quanto tempo você tem?

[Naylor1993]

In a previous sentence it told me that 'tem' went with 'ele/ela' and 'tens' went with 'você'.

[Paulenrique]

The verbs are conjugated the same way for ele, ela and você. Tu tens, você tem.

[TaliaKG]

Why doesn't "quanto tempo tem?" work? The computer says I have to use "você", but is that correct? I didn't think I had to use the subject if the verb is conjugated correctly...

[Paulenrique]

For not confusing with ele, ela, isso, etc it's better to use você

[amckel]

em português europeu, quanto tempo é que tens é correto não é?

[Paulenrique]

Yes. Unfortunately i don't think they accept that...

[Celso_Cavalcante]

seria quanto tempo tens tu ou quanto tempo tu tens.. as duas estriam corretas em PT europeu, mas a bandeira no idioma é a do Brasil, portanto a maneira correta mesmo seria quanto tempo você tem?

Can you also say 'Quanto tempo tem voce?'

[Paulenrique]

Yep, although it is not very used...

[kjw860]

Cool, thanks. That's one that the computer won then!

[Paulenrique]

Hehehe....

[StR.]

I put quanto tempo tu tens. what would be the sentence normally used? duolingo should tell me when my answer is uncommon ;)

[Paulenrique]

Tu isnt used that often, but você

[BrandnkW]

Tu is commonly used, more so, in southern Brazil, where there is a little more Spanish influence. Most of the rest of Brazil commonly uses voce.

[Paulenrique]

In southeast you'll find that in places as Santos and Rio de Janeiro
