From looking, I say A is because it's a multiple of 3:4:5. There are many sites that list all triples.
The wheel has 16 spokes.
There will be 16 spaces between the spokes.
See attachment. There are 8 spokes and 8 spaces between them.
Similarly, in the other, there are 16 spokes and 16 spaces.
you can see that the number of spaces between the spokes is equal to the number of spaces.
Answer: The fish can jump 5m high.
Step-by-step explanation:
Given that
s = 3h
where
h = the height(cm) the fish jumps out of the water
and s = speed of the fish(meters per second) then
3 must have seconds as its unit.
Now, If the fish is swimming at 15 meters per second
Then the fish can jump =
s= 3h
15m/s =3h
h= 15m/s/3s
h= 5 meters
