(i) It is the product of a pure number and a vector (velocity). Hence the unit of product is the same as that of vector, i.e., the product is a velocity of 85 km/h, towards east.

(ii) It is the product of a scalar (time) and a vector

(velocity). Hence the unit of the product will be hX (km/h). Thus the product is a displacement of magnitude 85 km, towards east

# What is the differences between the following two data ? (i) 85 km/h east, (ii) (8 h) (5 km/h east)
