Given :
Total distance = 100m
Total time taken = 15minutes
We need to find out the average speed of tortoise in km/h.
Concept used :
1km = 1000m
60 min = 1 hour
So now,
Average speed = Total distance travelled/Total time taken
→ Average speed = 0.1/0.25
→ Average speed = 1/25 × 100/10
→ Average speed = 4/10
→ Average speed = 0.4 km/h
Hence, the average speed of tortoise is 0.4 km/h

Answer:
Given :-
To Find :-
Formula Used :-
[tex]\clubsuit[/tex] Average Speed Formula :
[tex]\small \bigstar \: \: \sf\boxed{\bold{Average\: Speed =\: \dfrac{Total\: Distance\: Travelled}{Total\: Time\: Taken}}}\: \: \: \bigstar\\[/tex]
Solution :-
First, we have to convert distance m into km :
[tex]\leadsto \sf Distance =\: 100\: m\\[/tex]
[tex]\leadsto \sf Distance =\: \dfrac{100}{1000}\: km\: \: \bigg\lgroup \bf 1\: m =\: \dfrac{1}{1000}\: km\bigg\rgroup\\[/tex]
[tex]\leadsto \sf\bold{Distance =\: 0.1\: km}\\[/tex]
Again, we have to convert the time m into h :
[tex]\implies \sf Time =\: 15\: minutes\\[/tex]
[tex]\implies \sf Time =\: \dfrac{15}{60}\: hours\: \: \bigg\lgroup \bf 1\: minutes =\: \dfrac{1}{60}\: hours\bigg\rgroup\\[/tex]
[tex]\implies \sf\bold{Time =\: 0.25\: hours}\\[/tex]
Now, we have to find the average speed of tortoise in km/h :
Given :
According to the question by using the formula we,
[tex]\small \dashrightarrow \mathcal{Average\: Speed =\: \dfrac{Total\: Distance\: Travelled}{Total\: Time\: Taken}}\\[/tex]
[tex]\dashrightarrow \sf Average\: Speed_{(Tortoise)} =\: \dfrac{0.1\: km}{0.25\: h}\\[/tex]
[tex]\dashrightarrow \sf\bold{\underline{Average\: Speed_{(Tortoise)} =\: 0.4\: km/h}}\\[/tex]
[tex]\therefore[/tex] The average speed of tortoise in km/h is 0.4 km/h .
