Best ResponseYou've already chosen the best response.0One thing you might want to know when doing unit conversion is that you can use dimensional analysis, treating units like variables and multiply by 1. \[15 s = 15 s (1) = 15s(\frac{1hr}{60 min})(1)=15s(\frac{1hr}{60 min})(\frac{1min}{60s})=\frac{15}{3600}\]

Best ResponseYou've already chosen the best response.0By the factor label method. There are 60 seconds in a minute and 60 minutes in an hour. 15 seconds x (1 minute/60 seconds) x (1 hour/60 minutes) = your answer Soon enough you'll realize that 60x60=3600 and so there are 3600 seconds in 1 hour. Then you will only need 1 conversion ratio; 15 seconds x (1 hour/3600 seconds) = your answer
