In the 2004 summer Olympics, the united states women's 4x100 meter freestyle relay team, won a silver medal.
Each of the 4 team members, Natalie Coughlin, Amanda Beard, Jenny Thompson, Kara Lynn Joyce swam 100 meters.
Their winning time was 3:59.12 minutes (3 minutes and 59.12 seconds). What was the team's average speed in miles per hour.
:
Convert 400 meters to ft: 3.281*400 = 1312.4 ft
Convert 1312.4 ft to miles: 1312.4%2F5280 = .24856 miles
:
Convert 3 min, 59.12 sec to minutes 3 + 59.12%2F60 = 3.9853 minute
Convert 3.9853 min to hrs: 3.9853%2F60 = .06642 hrs
:
Speed = dist/time
Find mph: .24856%2F.06642 = 3.74 mph average speed of the team
