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: {{{1312.4/5280}}} = .24856 miles
:
Convert 3 min, 59.12 sec to minutes 3 + {{{59.12/60}}} = 3.9853 minute
Convert 3.9853 min to hrs: {{{3.9853/60}}} = .06642 hrs
:
Speed = dist/time
Find mph: {{{.24856/.06642}}} = 3.74 mph average speed of the team
