One of the events at a swim meet is the 500 meter freestyle. Use conversion factors and dimensional analysis to determine the le
BARSIC [14]

Answer:

1) Distance in feet equals 1640.4 feet

2) Distance in miles equals 0.3107 miles.

Step-by-step explanation:

From the basic conversion factors we know that

1 meter = 3.2808 feet

Thus by proportion we conclude that

500meters=500\times 3.2808feet\\\\\therefore 500meters=1640.4feet

Similarly using the basic conversion factors we know that

1 mile = 1609.34 meters

thus we conclude that 1 meter =\frac{1}{1609.34} miles

Hence by proportion 500 meters = 500\times \frac{1}{1609.34}=0.3107 miles
