Asha drives her car 45 kilometres north. She stops for lunch and then drives 15 kilometres east. What distance did she cover? What was her displacement?

Distance= 60 km

Displacement= 47.43 km

Explanation:

Distance is the total length an object covered and is a scalar quantity while displacement is the shortest distance from the starting point to the end.

We can simply add up the values to get distance which is 60 km

But to calculate displacement we must use the Pythagoras theorem

45^2 + 15^2 = s^2

2025 + 225 = s^2

√2250 = s

47.43 km = s
