Question

Julie is preparing a speech for her class. Her speech must last between one-half hour and three-quarters of an hour. The ideal rate of speech is 150 words per minute. If Julie speaks at the ideal rate, which of the following number of words would be an appropriate length for her speech?

Accepted Answer

Since there are 60 minutes in an hour, we need a number of words between (12 60)150=4500 and (3460)150=6750. The only such choice is 5650.
