Answer:
It will travel 1 mile in 2 hours.
Step-by-step explanation:
First you will have to find the unit rate, which is how much miles does a boat travel in one hour. In order to do that you do,
1.5 / 3
So then you will get 0.5 miles in one hour.
Then you find out how long it takes to travel in 2 hours. You do that by doing
0.5 * 2
So you will get 1 mile
So your final answer is, the boat will travel 1 mile in two hours.
No method can prove that the Triangles are congruent .-.
Interval notation can be ( 2 , +<span>∞).
you could also use the "set builder" notation for {x | x> 2; x</span>∈ℝ}
