प्रश्न
A tortoise moves a distance of 100 metres in 15 minutes. What is the average speed of tortoise in km/h ?
Advertisements
उत्तर
Distance (d) = 0.1 km
Time (t) = `15/60` hr
= 0.25 hr
So, we can calculate the speed as :
`"Average speed" = "Total distance travelled"/"Time"`
Average speed for the entire journey :
= `0.1/0.25`
= 0.4 km/hr
