Answer:
107 m
Step-by-step explanation:
The total distance of 321 meters is the sum of the distance she has traveled and the distance she has left to travel. In terms of ratio units, it is 1+2 = 3. If 321 meters is represented by 3 ratio units, then each one is 321/3 = 107 meters.
The distance traveled of 1 ratio unit is 107 meters.
Sofia is 107 meters from the cliff when her traveled : remaining ratio is 1 : 2.
_____
Additional comment
Sofia manages a horizontal distance of 321/840 ≈ 0.38 of the height from which she starts. Modern paragliders are capable of glide ratios of 9.3 or better, so Sophi could land as far as 7812 meters from the cliff.
