Answer:
The snowboarder travels 270 m in 18 seconds.
Step-by-step explanation:
Given that,
A snowboarder travels 135 meters in 9 seconds.
We need to find how far will the snowboarder travel in 18 seconds.
9 seconds = 135 m
1 second = (135/9) m
In 18 seconds,
[tex]t=\dfrac{135}{9}\times 18\\\\=270\ m[/tex]
So, the snowboarder travels 270 m in 18 seconds.
