Final answer:
The correct distance between -5.47 and 5.47 on a number line is 10.94, not 5.47 as Jason says. To find the distance between two points, you must take the absolute difference between them, which results in a positive distance regardless of the direction.
Step-by-step explanation:
Jason says the distance between -5.47 and 5.47 on a number line is equal to 5.47. However, this statement is incorrect. To find the correct distance between two points on a number line, you must calculate the absolute difference between those points. In this case, you take the point 5.47 and subtract -5.47, which will give us the total distance.
The calculation is as follows:
5.47 - (-5.47) = 5.47 + 5.47 = 10.94
So, the correct distance between the two points is 10.94 units on the number line. Distance, being a scalar quantity, is always positive and does not have a direction associated with it.
