We have that by definition of properties of powers that is fulfilled:

Then, rewriting the expression:

Answer:

Usando las relaciones entre velocidad, distancia y tiempo, se encuentra que ella condujo a una velocidad media de 90,5 km/h.

La velocidad es:

División de decimales, o sea, seguimos multiplicando los números por 10 hasta que ninguno sea decimal:

Ella condujo a una velocidad media de 90,5 km/h.
