French language Q&A Forum

I have a question which comes from this exercise but is not directly related to the subject matter perhaps but is a listening issue that I have come across before and there must be a rule that I don't know about or that I do and just don't recognise the context: 

In reflexive verb video, which is in the last set of "your practice" offered after you complete the last written section; at 7'40" in the video, the lady says: "Et puis, qu'est qu' on fait quant on utilise l'imperatif..." but instead of saying "quand" she pronounces the "t" as if it were "quante" ...So I wonder if you could tell me what the rule is for pronouncing "quand" with a "t" at the end, since quant, is of course a different word...

I hope that makes sense. I look forward to hearing from you. 

Best regards,

Michael

correct answers in weekend challenge:

qui devrait nous livrer les fleurs dans l'apres-midi

tu prendras ta voiture le matin

these seem to me to be the same sentence structure.  Why is dans not used consistently?  what about in the evening or night?

anyone able to help me understand?  

thank you
