No, the sequence is algebraic.
Answer:
Distance he covers in
of an hour =
miles.
Step-by-step explanation:
Phillip rode his bicycle at
miles per hour.
To find distance he covers in
of an hour.
Solution:
Speed at which Phillip rides =
miles per hour
Time for which he cycles =
of an hour
Distance covered in miles 
To multiply mixed numbers we need to convert them to fractions.
![[A\frac{b}{c}=\frac{Ac+b}{c}]](https://tex.z-dn.net/?f=%5BA%5Cfrac%7Bb%7D%7Bc%7D%3D%5Cfrac%7BAc%2Bb%7D%7Bc%7D%5D)

⇒ 
⇒ 
Then we simply multiply the numerators and denominators.
⇒
Then we convert back to mixed fraction by dividing numerator by denominator and writing the quotient as whole number with fraction (remainder as numerator and denominator being the divisor)
⇒
miles.
∴ Distance he covers in
of an hour =
miles.
The grid lines will help you find an exact solution (assuming the two lines actually cross at a grid intersection point). However, the two lines may intersect somewhere off the grid lines which is when an estimation will be the next best thing.
A) 38*(1-20%)*(1-10%)=27.36
b)38*(1-30%)=26.6
c)Because in question one when you take off the 10% it is 10% of the already off price but when you take off 30% it is taking off from the original price
