Jose wandered for 2 hour with speed at 2 kilometers per hour.
The speed of an item, which is a scalar quantity in everyday usage and kinematics, is the size of the change in that object's position over time or the size of the change in that object's position per unit of time.
The instantaneous speed is the upper limit of the average speed as the duration of the time interval approaches zero. The average speed of an item in a period of time is equal to the distance travelled by the object divided by the duration of the period.
Given parameters:
Distancetravelled by Jose = 4 kilometer.
Speed of Jose = 2 kilometers per hour.
Now from definition of speed:
Total time taken = Distance travelled by Jose ÷ Speed of Jose
= 4 kilometer ÷ 2 kilometers per hour.
= 2 hour.
Hence, Jose wandered for 2 hour.
