Answer:
Perfect positive association is the answer :)
The average speed would be 600 km/hr.
Step-by-step explanation:
Let the original speed be 'x'
Let the decreased speed be 'x-200'
Distance = 600 km
Time increased by 30 minutes
According to question, it becomes,

So, The average speed would be 600 km/hr.
Yes and thank you for the points
We can automatically rule out both Right and Equilateral Triangles, this is because there is no 90 degree angle (Needed for a right triangle) and all three angles are not equal (needed for an equilateral triangle).
Looking a little deeper, we know that an isosceles triangle has two congruent (or same) angles. Meaning we can rule this one out as well.
This leaves option A) Scalene Triangle
And to check, we think about a scalene triangle, and we know it's a triangle that has 3 unequal sides, meaning that this could qualify!
Answer:
B
Step-by-step explanation:
B) because both result in the equation 8 x = 400, which simplifies to x = 50
