Answers: 2.1 Bob is driving from Notre-Dame-du-Laus, Quebec, Canada to New eld, Maine. He plans to average 50 miles per hour due to the tra c congestion in Montreal. e trip is 415 miles. How long will it take? Divide miles by miles per hour to get the result in hours. 415 / 50 = 8.3 hours. 2.2 A er an argument with his wife, Jim gets in his truck and drives 60 MPH for 4.5 hours before stopping for ice cream. How far is he from home? 60 x 4.5 = 270 miles. Jim will need a lot of ice cream for his trip home. He should probably get some for his wife too. 2.3 Jerry traveled 283 miles in 4 hours. e speed limit was 70 MPH. Did Jerry break the speed limit? 283 / 4 = 70.75 MPH. Jerry de nitely broke the speed limit. 2.4 If Bob eats 14 hotdogs in 17 minutes what is this consumption in hot dogs per minute? 14 / 17 = .823 hot dogs per minute. (If you answered 1.21 you transposed the numbers and accidently calculated minutes per hot dog.) If Bob can only eat .823 hot dogs per minute he will not be winning the contest next year. 2.5 Cooling capacity = 1 case / hour. X 4 cases = 4 hours. 2.6 ere are two ways to calculate this. You can convert the refrigeration capacity to TR / HR. 17/24 = .7 tons / hour. We can then multiply this by 8 hours. .7 x 8 = 5.6 tons / 8 hours. Or you can divide the TR per day by the portion of the day you have to perform cooling. 24/8 = .33 x 17 = 5.7 2.7 75 carcasses per day x 14 days = 1,050 carcasses 2.8 3 tons per day x .33333 days (8 hours) = 1 ton per 8 hours. 2.9 .017 TR / Min. x 60 (minutes per hour) = 1.02 TR / Hour x 24 (hours per day) = 24.48 TR per day. 2.10 It takes 1 BTU / Pound / Deg. F. We can calculate this as 1 x 14,000 x 15 = 210,000 BTU But the question asked for the answer in TR. We must rst break the BTU’s down into a time element. For this example, I chose BTU/Hr. 210,000 BTUs divided by 4 (the number of hours we have to accomplish the cooling) = 52,500 BTU per hour. A ton of Refrigeration can be measured as 12,000 BTU per hour. So, if we divide our total BTUs per hour (52,500) by our rate (12,000 BTU per Hour) we get 52,500 / 12,000 = 4.375 TR.
