The wave will travel of total of 6.67 miles in the 1 hour of duration.
What are the ratio and proportion?
The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given the wave travel
1/3 mile ⇒ 1/20 hour
Multiply by 20 on both sides
20/3 mile ⇒ 20/20 hour
6.67 miles ⇒ 1 hour
Hence "The wave will travel of total of 6.67 miles in the 1 hour of duration".
