Alan covered a total distance of 400 km + 700 km + 1200 km = 2300 km. ️
To calculate his displacement, we need to consider the straight-line distance from the starting point to the final destination. Using the Pythagorean theorem, we can find the displacement:
Displacement = √((700 km)^2 + (400 km + 1200 km)^2) = √(490000 km^2 + 1600000 km^2) = √(2090000 km^2) ≈ 1446.99 km.
Since 1 cm represents 100 km, the displacement would be approximately 14.47 cm. ✈️
