Answer:
55 m she is far from the beginning of the track
Step-by-step explanation:
The linear track begins at 0 m
Since She is at the 10 m mark while practicing for the race so the initial point becomes 10 m further from the 0 m point
After running she is at 45 m from the 10 m meter
Therefore, from the beginning of the track which is 10 m beyond from the initial point
Distance = (45m + 10m ) = 55 m
She is 55 m away from the beginning of the track.
