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.

250 miles is equivalent to 400 kilometers.
We have,
To find out how many kilometers are equivalent to 250 miles, we can set up a proportion using the given information that 5 miles are equal to 8 kilometers.
5 miles : 8 kilometers
We can set up the proportion:
5 miles / 8 kilometers = 250 miles / x kilometers
To solve for x (the number of kilometers in 250 miles), we can cross-multiply and then divide:
5 miles x (x kilometers) = 8 kilometers x 250 miles
5x = 2000
Dividing both sides by 5:
x = 400
Therefore,
250 miles is equivalent to 400 kilometers.
