Q5 of 15 Page 26

The height of a place A is 1800 m above sea level. Another place B is 700 m below sea level. What is the difference between the levels of these two places?

Given: - Height of A above sea level = 1800m


The height of B below sea level = 700m


To find: - Difference between the height of A and B


Let Above sea level height as + sign and below as –ve sign


Now to find the difference between levels add them with their sign



Hence (+ 1800) + (– 700)


= + 1100 metres
