8 trips and 810 miles each so 8*810 = 6,480 miles. With 7 miles/minute we have (6480 mi) * (1 minute/7 mi) which will get you a certain amount of minutes. Use that to change minutes into hours. Remember, there 60 minutes in an hour.

The reason I put the units here when solving is to show how they cancel out. This concept is called "dimensional analysis" which you will learn more about later.

plane can fly seven miles in one minute if they take eight trips and each trip is 810 miles. How many hours will it take? So  There are eight trips and each trip is 810. So that's a total of 6480 miles. So then use the proportion seven miles is 21 minute as 6480 miles is two X minutes so cross multiply here seven times X. Is seven X. One times 6480 is 6480. So X. Is going to be equal to  Approximately if we round to the nearest, I'm gonna change this to approximately if we round to the nearest Minute it would be 926 minutes. They're asking us for the answer in hours. So we'll take the 926 divided by 60. And that would give us approximately 15.42 hours.

That is correct. If you are going to stop at a decimal point, round to the nearest last digit. The answer is 15.4285 hours which rounds up to 15.4 hours if you are going to round to the nearest hundredth.
