The question asks for the unit rate when 1/4 of a kilometer is covered in 1/3 of an hour.
Recall that rate is the quotient of two quantities. In our case the numerator is the distance (1/4) of a kilometer, and the denominator is the time: 1/3 of an hour.
So, we perform the following division of fractions:
1/4 diided by 1/3 which is the same as: 1/4 times 3/1 = 3/4
and since we are asked for the UNIT rate, we do the actual division:
The unit rate is 0.75 km per hour.

Step-by-step explanation:
Answer:
Only one extreme value of f(x) is possible.
Step-by-step explanation:
We are given the quadratic function of independent variable x which is f(x) = x² - 7x - 6 ......(1)
Now. the condition for extreme values of f(x) is 
Hence, differentiating both sides of equation (1) with respect to x, we get
= 0
⇒ x = 3.5.
So there is only one value of x for which f(x) has extreme value which is x = 3.5.
Therefore, only one extreme value of the given function is possible. (Answer)
