Answer: Juliet is 55 m far from the beginning of the track point.
Step-by-step explanation:
Let the starting point of the track be O and the end point be P.
OP = 100 meter
Let the point marked 10 m be Q. From where Juliet starts practicing.
Distance covered by Juliet = 45 m from point Q to point R
Distance of the Juliet from start point O to point R:
OR = OQ + QR = 10 m+ 45 m = 55 m
Juliet is 55 m far from the beginning of the track point.
