Under the given conditions Maribel can reach her goal of the skate.
A collection of numbers and operations is an expression in mathematics. The following are the parts of a math expression that do a math operation:
Operator: An operator is a symbol that denotes a math operation, such as:
division, addition, subtraction, and multiplication.
Given total distance to skate = 1 and 1/2 = 3/2 miles
skates in morning = 9/10 miles
distance left to skates = 3/2 - 9/10
multiply and divide by 5 in 3/2 = (3 x 5)/(2 x 5) = 15/10
distance left to skates = 15/10 - 9/10 = 6/10
distance left to skates = 6/10 = 3/5
and skate 2/3 of 9/10 in afternoon,
2/ 3 x 9/10 = 3/5
so the left distance is 3/5 which she skates in the afternoon.
Hence she will reach her goal.

Answer
Find out the how many minutes are spent preparing.
To proof
As given
A recipe takes 90 minutes to make.
25 percent of the time is spent preparing the ingredients.
25% is written in the decimal form
= 0.25
Time spent in preparing = 0.25 × 90
= 22.5 minutes
Therefore the 22.5 minutes are spent preparing the ingredients.
Hence proved
Answer: 87.96π
