 we know that  time=displacement/velocity;

       since displacement=vector,  velocity=vector;

now, time=vector/vector;

which is equalo to vector

but time is a scalar why????????????????????????????????????

Vector/Vector is always dimensionless..... it ll cancel  out.... soo time is dimensionless... nd hence is a scalar...

The formula time = displacement / velocity is applicable for the magnitude of the vectors. Division of vectors is not defined.
