The automobile is traveling 20 km/h faster than the train. Thus, it will cover extra 1.8 km in 1.8/20 = 0.09 hours.
Since d = rt, the car will have traveled 0.09*95 = 8.55 km in this time.
-------------------------------------------------------------
Now, since the automobile and train are traveling towards each other, we have to add their speeds. 95 + 75 = 170 km/hr. This means the distance between the end of the train and the automobile is closing at 170 km/hr
1.8/170 = 0.0106 hr.
Since d = rt, the car will have traveled 0.0106*95 = 1.007 km in this time.
Answer:
1. A non example of a constant in physics is a value that changes. For example, the temperature of Hong Kong, let's say, is not a constant, since it changes and does not stay at the same value. It gets higher in the summer and lower in the winter.
2. An example of a constant in physics would be the gravitational acceleration of the Earth. Since the Earth's mass' changes is negligible when compared with the overall mass of the Earth (unless something big happens, of course, like a meteor or asteroid), the gravitational acceleration on Earth is largely unchanged, even constant from our viewpoint.
