Final answer:
Josh gains an elevation equal to his velocity, v meters per minute.
Step-by-step explanation:
Velocity is a vector quantity that describes the rate at which an object changes its position. It includes both the object's speed and the direction in which it is moving. Velocity is often represented by the symbol v and is measured in units like meters per second (m/s) or kilometers per hour (km/h).
In one minute, Josh gains an elevation equal to his velocity, v. So, if his velocity is v meters per minute, he will gain v meters of elevation in one minute of climbing.
