Answer:
27 miles
Step-by-step explanation:
The law of cosines can be used to find the distance between the boats. In 1 hour, one has traveled 28 miles, and the other has traveled 26 miles. The angle between their directions of travel is ...
180° -50° -70° = 60°
Then the distance c can be found from ...
c^2 = a^2 +b^2 -2ab·cos(C)
c^2 = 28^2 +26^2 -2·28·26·cos(60°) = 732
c = √732 ≈ 27.055
The boats are 27 miles apart after 1 hour.
The distance will remain constant. Then the time taken by Adam with an average speed of 60 miles per hour is 9 hours.
<h3>What is speed?</h3>
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
The formula can be written as
Distance = Speed × Time
The time it takes Adam to drive to Disney World varies inversely with his average rate of speed.
If it takes Adam 10.8 hours at an average speed of 50 miles per hour.
If the average speed is 60 miles per hour, then the time taken will be
The distance will remain constant.
S₂ × T₂ = S₁ × T₁
60 × T₂ = 50 × 10.8
T₂ = 9 Hours

Step-by-step explanation:
Pumping rate my be defined as the the rate ta which a liquid is pumped through a system. It is measured as the flow of the liquid at a unit time. It may be referred to as the capacity of the pump which defines how much liquid is being passed through the pump in a certain given time.
The pumping rate in mL/s refers to the amount of liquid passed in one second of time.

Comment and Answer
This is a very well laid out proof. It would good for you to see how carefully this this proof has been set up.
Step Three says
DE = DF ÷ 2
The problem is that at least 2 of the choices will work. I think the best reason is that it is the definition of bisect. The previous statement says in language what statement three says in algebraic notation. So statement 2 is the given statement. Statement 3 tells us that DE is 1/2 DF because it is bisected.
