Question A turtoise moves a distance of 100 metres in 15 minutes. What is the average speed of the tortoise in km/h

Answer: 0.4 km/h 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, [tex]s=\frac {d}{t}[/tex] 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, [tex]s=\frac {0.1}{0.25}=0.4 Km/h[/tex] Therefore, the speed is equivalent to 0.4 km/h Log in to Reply

Answer:0.4 km/h

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,

[tex]s=\frac {d}{t}[/tex]

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, [tex]s=\frac {0.1}{0.25}=0.4 Km/h[/tex]

Therefore, the speed is equivalent to 0.4 km/h
