Question

On her way home from school, Savannah rides in a bus for 15.3 minutes, traveling at an average velocity of 98 km/h, east. If the bus traveled in a single direction down a straight road during the 15.3 minutes, can the distance Savannah travelled be determined?

B
No, Savannah's instantaneous velocity at several points must be known.
Yes, by multiplying Savannah's average velocity by her total travel time
No, Savannah's acceleration must be known
D
Yes, by dividing Savannah's change in velocity by her total travel time.

Answer 1

B. No, Savannah's instantaneous velocity at several points must be known.

To determine the distance traveled by Savannah, we need to know the full path taken by the bus, including any turns or stops. We also need to know the exact velocity of the bus at all points during the trip, not just the average velocity. Since we have only been given the average velocity of the bus for a portion of the trip, we cannot determine the distance traveled by Savannah.
