Write an equation for... you answer 12 emails in 15 minutes... how many emails can you answer in 2 hours?

Answer 1

Using ratio & proportion, we can model this problem as 12 emails / x emails = 15 minutes / 120 minutes since 2 hours = 120 minutes and we must use the same units.. We cross-multiply and solve for x. thus

15x = 1440 -------------> x = 96 emails
