One of the events at a swim meet is the 500 meter freestyle. use conversion factors and dimensional analysis to determine the length of this race in: 2) a) feet. b) miles.

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

Similarly using the basic conversion factors we know that

1 mile = 1609.34 meters

thus we conclude that 1 meter = miles

Hence by proportion 500 meters = miles

3/6   and 9/18

step-by-step explanation:

i think the answer is a.( -3, -1 )
