Cars A and B, each moving at 70 km/h, are approaching one another on a straight highway. After how many seconds will they meet if they were initially 1 km apart?
Physics/ Science -
The distance between the cars diminishes at a rate of 140 km/h. If the initial separation distance is 1 km, the time to meet is 1/140 hour, or 25.7 seconds
