An athlete runs 12 laps on a 400m running track every day for 2 weeks. How many kilometers does she run in total?
400 meters/lap x 12 laps/day x 14 days is the total number of meters in two weeks.
Divide that by 1000 for kilometers
If a track athlete runs 12 kilometers, how far does she run in meters
To find the total distance in kilometers that the athlete runs, we need to convert the distance of 400 meters to kilometers and then multiply it by the number of laps.
First, let's convert 400 meters to kilometers:
1 kilometer = 1000 meters
So, 400 meters is equal to 400/1000 = 0.4 kilometers.
Next, we need to calculate the total distance she runs in a single day:
Number of laps per day = 12
Distance per lap = 0.4 kilometers
Total distance per day = Number of laps per day * Distance per lap
Total distance per day = 12 * 0.4 = 4.8 kilometers
Now, let's calculate the total distance she runs in 2 weeks:
Number of weeks = 2
Number of days per week = 7
Total distance in 2 weeks = Total distance per day * Number of days per week * Number of weeks
Total distance in 2 weeks = 4.8 * 7 * 2 = 67.2 kilometers
Therefore, the athlete runs a total of 67.2 kilometers in 2 weeks.
