Answer :
Answer:
Eudora ran from her home to her secret laboratory at an average speed of **x** km/h. She then took one of her jetpacks and flew to her school at an average speed of **y** km/h. Eudora traveled a total distance of **z** kilometers, and the entire trip took **t** hours.
To find out how long Eudora spent running, we need to divide the distance she ran by her running speed:
Time spent running = Distance / Running speed = z / x hours
To find out how long Eudora spent flying, we need to first subtract the distance she ran from the total distance to find the distance she flew, then divide this by her flying speed:
Distance flown = Total distance - Distance ran = z - z = z
Time spent flying = Distance flown / Flying speed = z / y hours
Therefore, Eudora spent z / x hours running and z / y hours flying.
