Acircular track begins at o meters and has a total distance of 100 meters. juliet starts at the 10-meter mark while practicing
for a race.
after running 45 meters, how far is she from the beginning of the track?
10 meters
35 meters
45 meters
55 meters

55 meters

Explanation:

She started at the 10 meter mark, and ran 45 meters.  So her final position is:

10 m + 45 m = 55 m

She is 55 meters from the beginning of the track (the 0 meter mark).

55 meters

Explanation:

If Juliet starts at the 10-meter mark while practicing  for a race, after running 45 meters, she is 55 meters from the beginning of the track.

10 m + 45 m = 55 m

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
