Ralph spends 15 1/3 hours per month playing tennis. How many hours does he play tennis in a year? (There are twelve months in a year.)

a. 182 2/3

b. 164

c. 184

d. 164 1/3

184 hours a year cause 15x12 is 180hours and 20x 12 is 240 minutes and 240 minutes is 4 hours so 180+4 is 184 hours

Number of hours that Ralph spends playing tennis in a month = 15 1/3 hours

= 46/3 hours

Number of months in a year = 12 months

Then

The total number of hours that Ralph spends playing tennis = (46/3) * 12 hours

= 46 * 4 hours

= 184 hours

So from the above deduction we can see that the total time spent by Ralph in playing tennis in a year is 184 hours. So the correct option among all the options given in the question is option "c". I hope the procedure is clear enough for you to understand.
