How long does it take an automobile traveling in the left lane of a highway at 65.0 km/h to overtake (become even with) another car that is traveling in the right lane at 40.0 km/h when the cars' front bumpers are initially 80 m apart?

Divide the initial separation distance by the relative velocity.

80 m/(105,000 m/h) = 0.000762 h = 0.457 min = 2.74 seconds
