Answer:

0.4 km/h

Step-by-step explanation:

Speed is defined as distance moved per unit time and can be expressed in either m/s or Km/h or miles/h

Mathematically,

$s=\frac {d}{t}$

where d represent distance covered and t is time taken

Taking d as 100 m and converting it into km, we divide by 1000 hence d= 0.1 km

Time is 15 minutes and to convert to hours we divide by 60 hence 0.25 hours

Speed,
$s=\frac {0.1}{0.25}=0.4 Km/h$

Therefore, the speed is equivalent to 0.4 km/h
