Best ResponseYou've already chosen the best response.0instead of confusing yourself just think about it as if you were filling up your pool asnd you really wanted to go swim do you decide to use both of them so it can go faster one of you freinds asks you about what time will it be done and and you give her an amout of min. whatr would you tell him/her?

Best ResponseYou've already chosen the best response.0that last part always used to get me... until I realized the the "155" took one full minute and we only needed "145" of those: 145  is the reminder of the minute which is close enough to 1 right :) 155
