Question

Four friends go on a bike ride, and they want to compare how fast each of them bikes. Shelby bikes 2 miles in 12 minutes. Owen bikes 6,160 yards in 18 minutes. Brinley bikes 4 miles in 1680 seconds. Jimmy bikes 7920 feet in 450 seconds.

Determine the order of their speeds from fastest to slowest.

Match each name on the left with the correct ranking on the right.

Answer 1

The determination of the order of their speeds from fastest to slowest and matching names with the correct ranking are as follows:

Order of Speeds:

Friends     Speed   Ranking

Jimmy       12 mph     1st

Owen      11.7 mph    2nd

Shelby      10 mph    3rd

Brinley    8.6 mph    4th

Data and Calculations:

                                       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

Common measurements:

1 mile = 1,760 yards

1 mile = 5280 feet

1 minute = 60 seconds

Conversions:

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

Converted Distance and Time:

                                  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.
