Answer 1

Find out the Xavier Munny eating rate in DVDs per minute .

To prove

As given

`1\ second = (1)/(60)\ mintues`

First convert 17 seconds into mintues.

`17\ second = (17)/(60)\ mintues`

Thus

`In\ (17)/(60)\ mintues\ Xavier\ Munny \ eat\ 20\ DVDs.`

`Xavier\ Munny\ eats\ per\ mintues = (20)/((17)/(60) )`

`Xavier\ Munny\ eats\ per\ mintues = {(20* 60)/(17) }`

`Xavier\ Munny\ eats\ per\ mintues = 70.6`

Therefore the eating rate in DVDs per minute is 70.6 mintues.
