Calculate the distance travelled by the car, if a car travels `4km` towards north at an angle of `45^(@)` to the east and then travels a distance of `2km` towards north at an angle of `135^(@)` to the est.
A. `6km`
B. `8km`
C. `5km`
D. `2km`
A. `6km`
B. `8km`
C. `5km`
D. `2km`
(a) As the distance is a scalar quantity. So, total distance travelled `=4+2=6km`
