Answer 1

Answer

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

To prove

As given

Xavier Munny 17 seconds to eat 20 DVDs.

As 1 mintues = 60 seconds

$1\ second = \frac{1}{60}\ mintues$

First convert 17 seconds into mintues.

$17\ second = \frac{17}{60}\ mintues$

Thus

$In\ \frac{17}{60}\ mintues\ Xavier\ Munny \ eat\ 20\ DVDs.$

$Xavier\ Munny\ eats\ per\ mintues = \frac{20}{\frac{17}{60} }$

$Xavier\ Munny\ eats\ per\ mintues = {\frac{20\times 60}{17} }$

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

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