How many words are there approximatley in a one minute presentation?

I have a Spanish speaking exam on Wednesday and it is 4-6 minutes long in total. To start off I have to bring a photo of my favourite sports person and describe it, where it is, who it is, background info etc for one minute before conversation with my teacher(the examiner) starts. How long is this approximatley? Allowing for thinking time etc would 105 words be enough? Some of it is quite complex language so they are hard to pronounce. This is how much I have prepared so I need to know if it is enough.
