What is distance?
The measurement of distance between two objects or points can be quantitative or occasionally qualitative. Distance in physics or common language can refer to a physical length or an assumption based on other factors.
Let, Sylvie is going on vacation. She has already driven 60 miles in one hour. She then travels for 7 hours at an average speed of 57 miles per hour.
In 7 hours Sylvie travel 7 x 57 = 399 miles.
So, the total distance is,
399 + 60 = 459 miles
