Question

Eudora ran from her home to her secret laboratory at an average speed of 12 km/h. Then she then took one of her jetpacks and flew to her school at an average speed of 76 km/h. Eudora traveled a total distance of 120 kilometers, and the entire trip took 2 hours.

Answer 1

Answer:

60 km/h

Step-by-step explanation:

Eudora ran from her home to her secret laboratory at an average speed of 12 km/h.

Then she flew to her school at an average speed of 76 km/h.

Total distance traveled by Eudora = 120 kilometers

Time taken in entire trip = 2 hours

We will calculate the average speed of Eudora.

Speed = $\frac{Distance}{Time}$

           =  $\frac{120}{2}$

           = 60 km/h

Eudora's average speed for entire trip was 60 kilometers her hour.

Answer 2

Her average speed = total distance / time taken = 120 / 2 = 60 km/h.
