I think it may be 1,680B but I'm not too sure...
Answer: It would be 28%.
Step-by-step explanation:
Viola is travelling on an inclined path up the hill which makes an angle of 6 degrees with the horizontal.
The horizontal distance covered by Viola will be equal to the horizontal component of the 170 m distance covered at 6 degrees.
So, the horizontal distance covered by Viola = 170 cos(6) = 169.1 m
Thus, Viola covered 169.1 m horizontal distance
