What would be the answer to the 3:15 clock question? 360 deg?

If you look at a clock and the time is 3:15, what is the angle between the hour and the minute hands? (The answer to this is not zero!)

Well, consider that 3 o'clock would be 90 degrees apart (the hour and minute hands exactly 15 minutes apart). Divide that by 3 to figure out how many degrees 5 minutes apart would be: 30 degrees (the distance between each big hourly number).

Then, finally, consider that at 3:15 the hour hand would be 1/4 of the way towards the next 5 minute interval (the big number 4), therefore the answer is 30 degrees divided by 4 which equals 7.5 degrees apart.

Damn, those are some fun math problems. I need to apply for a Google job.

Say an advertiser makes $0.10 every time someone clicks on their ad. Only 20% of people who visit the site click on their ad. How many people need to visit the site for the advertiser to make $20?

Easy, peasy.


$20.00
------- = 20% ----> 200 = 1/5 ----> 1000 people need to visit the site.
$0.10


Child's play.
