Respuesta :
5.5 c/m. Doesn't it feel good to have calculators near you?
Answer:
5.5cm/mins
Step-by-step explanation:
According to the table, it can be inferred that distance travelled by the snail is directly proportional to the time taken.
Let x be the distance travelled by the snail and y be the time taken.
Mathematically, x ∝ y
x = ky where k is the proportionality constant.
k = x/y
x1/y1 = x2/y2 = k
If x1 = 27.5, y1 = 5
If x2 = 66, y2 = 12
Substituting this values we have:
27.5/5 = 66/12 = 5.5
This shows that the proportionality constant is 5.5cm/min
