The points A and B represent numbers on a number line where 25000 is at left end, A is near it, 39000 is in middle, B is to the right of 39000, and 61000 is at right end. The distance between the points A and B is—

The number line shows 25000 to 61000 with intervals. The total span from 25000 to 61000 is 36000, divided into equal segments. Reading the positions of A (near 25000, approximately 28000) and B (approximately 50000), the distance between A and B works out to 22000 units. The answer is in thousands because the scale is in thousands.
