Your answer is 600. i hope this helps!
We know that
speed=distance/time
1) <span>Sarah rides her horse for 2 1/6 hrs with a constant speed of 6 km/hr
time=2 1/6 hrs----> 13/6 hrs
speed=6 km/h
distance=speed*time----> 6*(13/6)---> 13 km
2)</span><span>for another 2 hours and 5 minutes with a constant speed of 12 km/hr
time=2hrs+5 minutes----> 2+(5/60)--> 125/60 hrs
speed=12 km/hrs
distance=speed*time----> 12*(125/60)---> 25 km
3) find the </span><span>average speed for the total trip
total distance=13 km+25 km----> 38 km
total time=(13/6)+(125/60)----> (10*13+125)/60----> 4.25 hours
speed=38/4.25----> 8.94 km/hrs
the answer is
8.94 km/hrs</span>

Answer:
>180° (more than 180°)
Step-by-step explanation:
Angles are classified as ...
- acute: < 90°
- right: = 90°
- obtuse: > 90°
- straight/linear: = 180°
- reflex: > 180°
It seems that we're looking at definitions:
obtuse : >90° :: reflex : >180°
