Question
A snail covers a distance of 100 metres in 50 hours. Calculate the average speed of snail in km/h.
Solution
Distance (d) = 1000 m = 0.1 km
Time (t) = 50 hr
So, we can calculate the speed as :
`"Average Speed" = "Total distance travelled"/"Time"`
Average speed for the entire journey :
= `0.1/50`
= 0.002 km/hr
