Step-by-step explanation:

To calculate the walking rate, you have to think of the unit that the walking rate is in. Walking rate is most often in meters per second or kilometres per hour, so I'll explain both. The first one (m/s) is easy, since both are already in these units. The formula speed = distance/time can be used here, which gives 12/3 = 4 meters per second.

For km/h it is a little more difficult. 12 meters equals 12/1000 kilometers (which is 0.012), since there are 1000 meters in a kilometer. Then 3 seconds equals 3/60 minutes (which is 0.05 mins), which is 0.05/60 hours (which is 0.0083333). Using the formula now, the answer is 0.012/0.0083333 = 14/4 km/h
