An aircraft will travel a total distance of 6000 miles. The first part of the trip takes two hours, and the aircraft's average speed is 700 miles per hour. If the entire trip takes 12 hours, what is the aircraft's average speed, in miles per hour, during the second part of the trip?
O 383
O 442
O 530
O 460

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.

step-by-step explanation:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
