Quantity 1: velocity. Quantity 2: speed. Classify each as a scalar or a vector.
You've already sorted the motion quantities into scalars and vectors. That sorted list matters when you pick a quantity for a real job: some jobs need a direction, and some do not.
Take one hiker on one walk, and vary the job. Predicting where she ends up depends on which way she walks: that job needs a vector, her velocity. Logging how much trail she covered needs only an amount: a scalar, her distance. Stating her pace needs only an amount too: a scalar, her speed.
An air-traffic controller must predict where a plane will be in five minutes. Which quantity about the plane's motion does the job need?
A courier charges for a delivery ride by the kilometer ridden. The charge depends only on how much path was ridden; direction never enters the price. An amount alone is enough, so a scalar does the job: the distance.
A fitness app must record how much ground a runner covered, whatever route she took. Which quantity should the app record?
A rescue coordinator must tell a helicopter where a drifting life raft will be in one hour. The predicted position depends on how fast the raft drifts and on which way it drifts. Direction matters, so the job needs a vector: the raft's velocity.
A ship's navigator must decide which way to point the bow to reach a lighthouse. Which quantity does the job need?
A student finds where a wandering robot ended up by reading its odometer: 'it drove 26 m, so it is 26 m from the start.' Which quantity did the job actually need?
For which job is a scalar all you need?
Job 1: reporting how much rope a winch has paid out. Job 2: reporting where a probe sits relative to its lander. Which kind of quantity does each job need?
