your velocity during the journey is 5,000 m/s
The given parameters;
The horizontal displacement = 5,000 m East - 1,000 m West = 4000 m
The vertical displacement = 3,000 m North
The resultant displacement is calculated as;
[tex]D^2 = 4000^2 + 3000^2\\\\D^2 = 25,000,000\\\\D = \sqrt{25,000,000} \\\\D = 5,000 \ m[/tex]
The velocity is the change in displacement per change in time;
[tex]V = \frac{5000}{1} \\\\V = 5,000 \ m/s[/tex]
Thus, your velocity during the journey is 5,000 m/s
