Distance = speed ×time
First convert 15 minutes into hour as the unit need to be same before multiplying
So 15min =15/60 hour =1/4 hour
So distance =12×1/4 =3 km
How I wrote km?
As we multiply the digits ,units also get multiplied . therefore we brought them in same units.
As in above case
Distance=speed ×time
Unit of Distance =unit of speed × unit of time
Unit of Distance=(km/hr) ×hr =km
Hence km is unit.
