Question 1126109: Four girls, Georgia, Henrietta, Isabelle, and Jackie, all enjoy running. They are discussing running when Georgia ask "What is your fastest speed that you have ever gone"? The girls answer in the following way: Georgia, "I ran 100 meters in 20 seconds." Henrietta, "I can run 7 miles an hour." Isabelle, "I ran 5 kilometers in 30 minutes." Jackie, "I ran a half marathon in 2 hours." Convert the distances to kilometers and put the girls in order from slowest to fastest.

Bad example. If you choose to ignore that, then you only need to use:

60 minutes is 1 hour.
60 seconds is 1 minute.
1 mile is 5280 feet.
1 marathon is 26 miles. (or 1 marathon is 42.195 kilometers).
100 cm is 1 meter.
2.54 cem is 1 inch.
1000 meters is 1 kilometer.

Use those which fit to convert each person's speed into KILOMETERS per HOUR (or whichever common unit you prefer). Try to do all of the conversions on your own. Example of Georgia,

Georgeia: %280.1%2F20%29%28kilometers%2Fseconds%2960%28seconds%2Fminute%2960%28minutes%2Fhour%29
%280.1%2A60%2A60%29%2F20
0.1%2A3600%2F20
360%2F20
36%2F2
18,kilometersperhour
