road. If the distance towards east is represented by positive integer then, how will you represent the distance

with solution please urgent​

Answer 1

Answer:

1. According to the no. line Sonia moves towards east is represented by positive and west is represented by negative integer

Distance from A to B = 20 Km

Distance from B to C = 30 km

Distance from A to C = 20-3020−30

Sonia is at final position from A to C is = -10\ Km−10 Km

2.The plane is flying at the height of 5000 m above the sea level

Distance of the plane from sea level = 5000\ m

Also, the submarine floating 1200 m below the sea level

Distance of the submarine from sea level = -1200\ m

Distance between them = [5000-(-1200)]\ m

6200\ m
