Okay, here we're told that a boat is traveling 8 .37 nautical miles and moving at a speed of 9 .3 nautical miles per hour.
00:09
And they want to know how long will it take the boat to reach its destination, which is 8 .37 miles away, and at what time if it left at 2 .42 p .m.
00:25
Okay, so first we'll find out how long it's going to take.
00:28
So to do that you're going to use the formula distance equals rate times time.
00:34
Because we have the distance, which is 8 .37, and we have the rate, which is 9 .3, we're looking for time.
00:44
So if we do 8 .37 divided by 9 .3, we get 0 .9 for t.
00:53
So 0 .9 hours.
00:56
So now if we think about that in minutes, if i take 0 .9, 0 .9 hours, and i multiply by 60, because it's 60 minutes every one hour, hours will cancel, and if i do 0 .9 times 60, that'll leave me minutes.
01:14
So 0 .9 times 60 is 54 minutes.
01:19
So that's part a...
