Final answer:
By using the formula for average velocity, which is the displacement divided by the time, and substituting the given values (625 km and 250 km/h), we find that the airplane trip took 2.5 hours.
Step-by-step explanation:
To determine how long the trip took for an airplane traveling at an average velocity of 250 km/h [E] with a resulting displacement of 625 km [E], we use the formula for average velocity (Vavg), which relates velocity, displacement, and time.
The formula for average velocity is:
Vavg = displacement / time
By rearranging the formula to solve for time, the equation becomes:
time = displacement / Vavg
Substituting the given values:
time = 625 km / 250 km/h
Following the calculation:
time = 2.5 h
Therefore, the trip took 2.5 hours.
