7. I used to run at a pace of 8.3 mi/hr. Convert that speed to kilometers per minute. a. How many minutes did it take me to run one kilometer? b. What is my pace in minutes per mile? (HINT: You are starting over in this problem, get numbers from the original question) 8. My dog Bucky used to eat 2.5 cups of food per day. Each cup of dog food weighs about 0.261 lbs. If a 40 lb bag of food costs $38, how much money will it cost to feed him for his life span of about 14 years?

7. What number should be reported to best reflect the temperature according to the thermometer? A. 21.7 °C B. 21.70 °C CC 22°C ........ 25 20 15 D. 21 °C 22.7°C E. undergo the

7. 12.0 mL of A weighs 10.8 g; and 16.0 mL of B weighs 14.4 g. A. A has a higher density than B. B. B has a higher density than A. C. A and B have equal densities. D. There is insufficient information to answer this question.

1. Which is higher: 85.7 °F or 28.9 °C ? 2. The boiling point of a liquid is calculated to be 325 K. What is this temperature on the Celsius and Fahrenheit scales?  3. The melting point of an unknown solid is determined to be 33.0°C. What is this temperature on the Fahrenheit and Kelvin scales?

A jet airplane reaches 661. km/h on a certain flight. How long does it take to cover 416. m? Set the math up. But don't do any of it. Just leave your answer as a math expression. Also, be sure your answer includes all the correct unit symbols. time 10

6. Every morning I use 1 cup of Bisquick pancake mix to make pancakes for my kids. How many boxes of Bisquick do I use in 1 year? 7. How many meters per second (m/s) is a car moving if it is going 55 MPH? Hints: "MPH" is miles per hour or (miles/hour). A car that moves at 55 MPH is going 55 miles for every 1 hour, and the car travels 110 miles after 2 hours, 220 miles after 4 hours, etc. 110 miles 110 miles per hour = 55 miles per hour. 2 %3D Notice that the miles divided by time is 2 hours So, if a car is going 55 miles per hour, convert 55 miles into meters, convert 1 hour into seconds, and meters or then divide the answers to calculate meters per second (or nd second -).
