Answer 1

Answer:

3 m

Step-by-step explanation:

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
