Answer: 1:30 PM

How many gallons?    3/4 = .75    .75 x 10 = 7.5 
gallons

How many ounces per gallon?  128 ounces per 
gallon

How many ounces in 7.5 gallons?   7.5 x 128 = 960 
oz.

How many glasses?   1 glass = 8 oz.    960/8 = 120 
glasses

45 seconds x 120 glasses = 5400 seconds

5400/60 = 90 min.   12:00 + 90 min. = 1:30 PM

School: Indian Valley Middle School

Answer: 1:30 PM

128 oz. per gallon

1280 (10 gal.) x 3/4 = 960 oz

960 oz. / 8 = 120 trips

120 x 45 seconds = 5400

5400/ 3600 = 1.5 hours

Noon + 1.5 hrs. = 1:30 PM

10 x .75 = 7.5      128 x 7.5 = 960      960/8 = 120

120 x 45 = 5400     5400/60 = 90       12:00 + :90 = 
12:90
                                        
                                        12:90 - :60 = 12:30
                                                                                                                        
                                
                                        12:30 + 1:00 = 1:30 PM
