A circular running track is 14 of a mile long. Elena runs on this track, completing each lap in 116 of an hour. What is Elena’s running speed? Include the unit of measure

Sagot :

Answer:

The wording is quite confusing, but here it goes

Step-by-step explanation:

T(track)= 14 of a mile. 1 mile is 5280 feet. If Elena is running each lap at 116 of an hour, (116%?) then 16% of 60 is 9.6 minutes, so each lap takes 69.6 minutes. One lap is 1312 feet, so 5280/1312= 4.02, so she can run 4 laps, which will take her 278 minutes. So 1312 is 24% of a mile, and she is running at .24 mph.
