The distance traveled by Davis family = 35 miles
Time taken to cover the distance =
hour
Speed = Distance
Time
Speed = 
Speed = 
So, speed = 70 miles/hour.
At 2:00 pm, the family destination was 245 miles away.
So, the number of hours, when the family was 245 miles away = 
= 3.5 hours
So, after 3.5 hours, that is at 5:30 pm, the Davis family will be 245 miles away.
A rational number is any number that can be written as "a/b," where "a" is an integer, and "b" is not equal to zero.
Rational Number:
a
--- → "a" is an integer → "b" ≠ 0
b
Answer:
Step-by-step explanation:
Independent Variable
The independent variable is the condition that you change in an experiment. It is the variable you control. It is called independent because its value does not depend on and is not affected by the state of any other variable in the experiment. Sometimes you may hear this variable called the "controlled variable" because it is the one that is changed. Do not confuse it with a "control variable," which is a variable that is purposely held constant so that it can't affect the outcome of the experiment.
Dependent Variable
The dependent variable is the condition that you measure in an experiment. You are assessing how it responds to a change in the independent variable, so you can think of it as depending on the independent variable. Sometimes the dependent variable is called the "responding variable."
The cardinality of the union between two sets is given by

In fact, if an element is in both A and B, it is counted in both N(A) and N(B), so we're counting it twice. By subtracting the cardinality of the interserction, we're taking back one of these "extra-counted" element, and the count is correct. In your case, the numbers are

This means that the two sets cover, without repetitions, 43 of the 66 elements in the sets. So, there are

elements which are in neither A nor B
