The determination of the order of their speeds from fastest to slowest and matching names with the correct ranking are as follows:
<h3>Order of Speeds:</h3>
Friends Speed Ranking
Jimmy 12 mph 1st
Owen 11.7 mph 2nd
Shelby 10 mph 3rd
Brinley 8.6 mph 4th
<h3>Data and Calculations:</h3>
Shelby Owen Brinley Jimmy
Distance biked 2 miles 6,160 yd 4 miles 7,920 ft
Time taken to bike 12 minutes 18 minutes 1,680s 450s
<h3>Common measurements:</h3>
1 mile = 1,760 yards
1 mile = 5280 feet
1 minute = 60 seconds
<h3>Conversions:</h3>
Owen's 6,160 yards = 3.5 miles (6,160/1,760)
Jimmy's 7,920 feet = 1.5 miles (7,920/5,280)
Brinley's 1,680 seconds = 28 minutes (1,680/60)
Jimmy's 450 seconds = 7.5 minutes (450/60)
Speed = Distance/Time
<h3>Converted Distance and Time:</h3>
Shelby Owen Brinley Jimmy
Distance biked 2 miles 3.5 miles 4 miles 1.5 miles
Time taken to bike 12 minutes 18 minutes 28 minutes 7.5 minutes
Speed 10 mph 11.7 mph 8.6 mph 12 mph
(2/12 x 60) (3.5/18 x 60) (4/28 x 60) (1.5/7.5 x 60)
Thus, their order of speeds shows that Jimmy bikes the fastest while Brinley bikes the slowest.
