Answer:
243 miles
Step-by-step explanation:
A hurricane traveled 180 miles in 4 hours.
Hurricane traveled in 1 hour =
=
The average rate at which the hurricane is moving slows by 10%
So, Distance traveled by hurricane in hour after 10% slow rate =
The distance that the hurricane will travel in the following 6 hours =
So, Option C is true
Hence the distance that the hurricane will travel in the following 6 hours is 243 miles

Answer:
It is Commutative
Step-by-step explanation:
An operation ∆ is said to be Commutative if a∆b=b∆a ∀ a,b ∈ ℝ.
Given the operation ∆ defined by:
a∆b=a X b
a∆b=
=3
Similarly, for the right hand side.
Therefore:
b∆a=
=3
These are the two ways of solving this problem and we have in fact shown that the operation is commutative as:
a∆b=b∆a=3
