PART E PAGES 639–642

1. The winner in a recent Los Angeles Marathon ran the 26-mile race
   in 2.23 hours. How many yards per minute did he run?


2. A swimming pool can be filled at the rate of 25 liters per minute
   using a special pump. About how many hours will it take to fill
   a pool that holds 5,000 gallons of water?


3. A water plant can process 25 million gallons of water a day. About
   how many liters of water per hour does it process?

Convert each rate. Round to the nearest hundredth if necessary.

4. 55 mi/h =  ft/s 5. 8 gal/h =  L/min 6. 12 m/min =  ft/s


5. 50 g/cm =  oz/in. 8. 15 qt/h =  gal/min 9. 2.6 oz/50 lb =  g/kg


6. 50 mi/h =  ft/h
   11. 5 ft/s =  ft/h 12. 36 m/h =  ft/min

PART F PAGES 643–648

Complete. Round to the nearest hundredth if necessary.

1. 8 yd^2 =  ft^2 2. 12 m^2 =  cm^2 3. 450 mm^2 =  cm^2


2. 1,000 in^2 =  ft^2 5. 18 ft^2 =  in^2 6. 100 ft^2 =  yd^2


3. 6.5 cm^2 =  mm^2 8. 8 cm^2 =  mm^2 9. 8.2 ft^2 =  in^2


4. 12 m^2 ≈  ft^2 11. 6.5 yd^2 ≈  m^2 12. 50 cm^2 ≈  in^2

Complete. Round to the nearest hundredth if necessary.

13. 3,000,000 cm^3 =  m^3 14. 100 mm^3 =  cm^3 15. 100 in^3 =  ft^3


14. 5 ft^3 =  in^3 17. 100,000,000 cm^3 =  m^3 18. 4,000 in^3 =  ft^3


15. 13.5 yd^3 =  ft^3 20. 8.4 cm^3 =  mm^3 21. 1,000 in^3 =  ft^3
