Velocity: 120 miles/hr
Now Distance= Speed × Time
Now Velocity and speed have the same magnitude. Velocity being a vector quantity has a definite direction. Whereas speed is a scalar quantity,it indicates only the magnitude an doesn't define any direction.
Hence Distance = Velocity x time
Distance = 3.5 × 120 = 420 miles
[tex]\\ \sf\longmapsto Displacement=Speed(Velocity)\times Time[/tex]
[tex]\\ \sf\longmapsto Displacement=120(1.6)[/tex]
[tex]\\ \sf\longmapsto Displacement=192km[/tex]
