The displacement must be the same for both hikers. Displacement refers to the change in position from the starting point to the ending point, regardless of the path taken. Since both hikers arrive at the same destination, their displacement will be the same.
The other quantities listed - average velocity, average speed, acceleration, and distance - can vary depending on the specific path taken and the time taken to reach the destination, so they do not have to be the same for both hikers.
Two hikers set out from the same spot and arrive at the same destination but they take different routes. Which of the following quantities must be the same for both hikers?
a) average velocity
b) displacement
c) average speed
d) acceleration
e) distance
