How many minutes will it take a rescue boat traveling 12 mi/hr to reach a boat 3,687ft away to the nearest minute?

I know the unit conversion ratios I will need are 12mi/1hr, 5280ft/1mi, and 1hr/60min. But, I'm not sure what to do from there.

Then divide 3687 by that?

16shuston · Answer

Okay I got the same thing, and yes you do. Did you get .28 minutes?

adamk · Answer

@16shuston No... I got 3.49 minutes. Which reduces to 3 minutes for the nearest minute.

16shuston · Answer

okay. what does your set up look like?

adamk · Answer

3687/1056

16shuston · Answer

okay, sorry i was in a different setting on my calculator. but you are right. Im sorry :/

adamk · Answer

@16shuston Alright, cool. And 3.49 to the nearest minute is 3 right?

16shuston · Answer

if that was rounded to the nearest minute it would first round to 3.5 which means then you would round up to 4

adamk · Answer

Oh, ok. Didn't know if I was supposed to round to the tenth first and then the nearest minute.

16shuston · Answer

adamk · Answer
