Answer: $0.05\ \frac{mi}{min}$

Step-by-step explanation:

For this exercise you need to remember the following formula:

$V=\frac{d}{t}$

Where "V" is the speed, "d" is the distance and "t" is time.

In this case, according to the information given in the exercise, you know that:

- James leaves his school at 3:15 and arrives at the park at 3:25. Then, you can identify that the time it takes him to go from his school to the park is:

$t=10\ min$

- The park is 0.5 miles from James' school. Therefore, you can identify that "d" is:

$d=0.5\ mi$

So, knowing those values, you can substitute them into the formula:

$V=\frac{0.5\ mi}{10\ min}$

Finally, evaluating, you get the following result:

$V=0.05\ \frac{mi}{min}$

Please answer question 8(ii) a & b only.

If the value depreciates by 20% each year it means that each year the value = 80% ( or 0.8) of the value the previous year

Lets suppose the mower cost $200 then after 5 years value would be 200 * (0.8)^5 = $6.5.54 so its not worthless

b) aFTER 2 YEARS THE FACTOR WOULD BE (0.8)^2 = 0.64
He multiplies by 0.64 Aswer
