I am traveling 30 mph to the west in a car on the way to my grandmother's house. The trip is taking a long time and I want to cut the remaining travel time in half.what is the use of multiplying and dividing a vector by a scalar?

I can therefor multiply my velocity vector by 2 to get the new vector of 60 mph to the west.

what is the use of multiplying and dividing a vector by a scalar?

They scale the magnitude of the vector. For example, a scalar with a value of ##2## can be used to scale the magnitude up by a factor of ##2## or down by a factor of ##2##, by multiplying or dividing, respectively, by ##2##.
