Final answer:
The closing speed of two vehicles each traveling at 50 mph towards each other is 100 mph, which is the sum of both vehicles' speeds.
Step-by-step explanation:
If two vehicles are approaching each other and each vehicle is traveling at a speed of 50 mph, the closing speed between the two vehicles is the sum of both vehicles' speeds. So, the closing speed would be 50 mph + 50 mph, which equals 100 mph. Closing speed is a term used to describe the relative speed of two objects moving towards each other. In this scenario, each driver would see the other vehicle approaching at this combined speed. It's important to note that closing speed can significantly affect the time available for reaction and the severity of a collision should one occur.
