Awoman traveled 2439.1 miles in 17 hours 10 minutes. find the average speed of her flight in miles per hours.

the average speed of the flight is 142.1 miles per hour

Step-by-step explanation:

Total number of miles that the woman travelled is 2439.1

The total time that she spent on the flight is 17 hours 10 minutes. There are 60 minutes in one hour. Converting 17 hours 10 minutes to hours, it becomes

17 + 10/60 = 17 + 0.167 = 17.167 hours

Average speed = total distance/total time

Therefore, the average speed of her flight in miles per hour would be

2439.1/17.167 = 142.1 miles per hour

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
