Question

AcarTravels at a speed of 60 km per hour due north and the other at a speed of 60 km per hour due to East are velocities are equal​

Answer 1

As velocitiy is a vector quantity. vector quantities have both magnitude and direction. Here magnitude is same but direction is different. we can write V1 = 60j and V2 = 60i. hence velocities are not equal. we can just compare the magnitude and magnitude wise they are equal.
