1) An average soccer player travels 7 miles during a game. A typical field is 109 meters long. How many times did the average soccer play travel the length of the field? Round your answer to the nearest tenth.

2) The dosage for a certain drug calls for 25 mg per kg per day and is divided into two doses (1 every 12 hours).

 If a person weighs 221 pounds, how much of the drug should be given each dose?

Answer:

1) 1000 m = 0.6214 miles

7 miles (1000 m / 0.6214 miles) x (1 field length/109 m) = 103.3 times

2) 25 mg / kg person - day x (0.4536 kg/1 lb) x 221 lb x (1 day/2 doses) = 1253.1 mg per dose
