A plane is flying at 5500m. A submarine is floating 3500m below the sea level. What is the distance between them in km

Open in App

Solution

plane = 5500 m = 5.5 km

submarine = -3500m = -3.5 km ( negative sign is used because it is below sea level and plane is above sea level)

distance between them = 5500 - (- 3500)m = 5.5-(-3.5) km = 5.5 + 3.5 = 9 km
