Since the question is asking for the time units to be in hours, you want to convert 30 minutes to an hour; 0.5
We’re able to use the basic motion formula for velocity to work out this question.
Velocity = distance / time
Velocity = 5 / 0.5
Velocity = 10km/h
Therefore, Stanley’s average speed was 10 kilometres per hour. :)
600 ---> 250
600 - 250 = 350
350 / 5 = 70
Average decrease in value per year: $70

Answer:

Step-by-step explanation:
Because we are told equivalent expressions for y and z we can plug those in to 2(y+z).

Then simplify by combining like terms of the expressions. Values ending in x^2 can be combined with each other.

Now we can distribute the 2 by multiplying each value in the parentheses by 2.
