Eudora spent 0.5 hours in running and 1.5 hours flying using her jet-pack.

Step-by-step explanation:

Let x represent time spent in running.

We have been given that the entire trip took 2 hours, so time spent in flying the jet-packs would be .

We know that distance is equal to speed times time.

Eudora ran from her home to a secret laboratory at an average speed of 12 km, so distance traveled by running would be .

Eudora took one of her jet-packs and flew to her school at an average speed of 76 km, so distance covered by jet-packs would be .

We are told that Eudora traveled a total distance of 120 km. We can represent this information in an equation as:

Combine like terms:

Divide both sides by :

Therefore, Eudora spent 0.5 hours in running.

Upon substituting in expression for time spent in flying jet-packs, we will get:

Therefore, Eudora spent 1.5 hours flying using her jet-pack.
