PARAGLIDING Sofia paraglides off a cliff that is 840 meters above the ground. She lands a horizontal distance 321 meters away from the base of the cliff.
When the ratio of the distance Sofia has traveled to the distance she has left to
travel is 1:2, what is her horizontal distance from the cliff?

9514 1404 393

  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.

for future students the answer is b

hope i
