Answer:
<em>Anna drove at an average speed of 49.73 km/h</em>
Step-by-step explanation:
<u>Average Speed</u>
If an object moves at different speeds to cover a certain total distance dt in a total time tt, the average speed is:

Anna drives a total distance of dt=45 km each day. One day she drives a distance of d1=25 km at v1=82 Km/h. The time taken for that distance is:

She takes t2=36 minutes to drive the remaining distance. 36 minutes is 36/60=0.6 h, thus the total time is:

The average speed is:

Anna drove at an average speed of 49.73 km/h
Answer:
there is no solution to this eqn.
this eqn brings us to 2=3 which certainly is false..
the number of degree in the central angle
Answer:
We would need more information to figure out who or what ate the numbers. It gives no examples of things that would. I hope you understand this. Have a great day :)
