Question:

Please help?

I have tried everything I know ofA recycling center can recycle 1500 pounds of aluminum in one hourHow many hours will it take them to recycle 10 tons of aluminum? Round your answer to the nearest tenth(Hint: 1 ton 2000 pounds.)

Answer:

convert the pounds to tons first 1500 (pounds per hour)/2000 (pounds in a ton) .75 tons per hour 10 (tons to process) / .75 (tons per hour) 13.33 hours or 13 hours and 20 minutesThe nearest 10th is 13.3 hoursWe could also convert our 10 tons to pounds and work this way10 (tons) 2000 (pounds in a ton) 20,000 pounds 20,000 (pounds to process) / 1500 (pounds per hour) 13.34 hours or 13 hours and 20 minutesWe can check the work: 13.3 hours of processing .75 tons per hour we'd do 13.3 .75 which is 9.975 (remember, we rounded so this is 10) so, your formula is pounds to process / pounds per hour hours needed tons to process / tons per hour hours needed we just have to remember to use either pounds or tons but we can't mix them in the same formula?
