Answer:
24 km/hr
Step-by-step explanation:
Speed is the rate of distance traveled in a defined time. Average speed is to take calculate the total distance travel at different speeds dividing by the total time taken.
Total Time = 4 hours
Total Distance = 68 km + 3 km + 25 km = 96 km
Average Speed = Total Distance / Total Time taken= 96 km / 4 hours
Average Speed = 24 km per hour

Step-by-step explanation:
it is not a function because 9 and three are a pair but so are 27 and 3. that makes it not a function

Answer:
-0.25y
Step-by-step explanation:
Simplifying
4x + 1y = 12
Solving
4x + 1y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1y' to each side of the equation.
4x + 1y + -1y = 12 + -1y
Combine like terms: 1y + -1y = 0
4x + 0 = 12 + -1y
4x = 12 + -1y
Divide each side by '4'.
x = 3 + -0.25y
Simplifying
x = 3 + -0.25y
