Here are the solutions to the problems:

Question 9 (Profit Calculation):

Identify the cost price and selling price.
Cost Price = sh 10,000
Selling Price = sh 12,000
Calculate the profit.
Profit = Selling Price - Cost Price
Profit = sh 12,000 - sh 10,000
Profit = sh 2,000

The profit was $\boxed{\text{sh 2,000}}$ .

Question 8 (Algebraic Equation):
Solve for $y$ :
$\frac{y}{2} - 3 = 5$
Add 3 to both sides of the equation.
$\frac{y}{2} - 3 + 3 = 5 + 3$ $\frac{y}{2} = 8$
Multiply both sides by 2.
$\frac{y}{2} \times 2 = 8 \times 2$ $y = 16$
The value of $y$ is $\boxed{16}$ .

Question 9 (Journey Duration):
Note the departure and arrival times.
Departure Time = 9:15 am
Arrival Time = 1:15 pm
Calculate the duration of the journey.
From 9:15 am to 12:15 pm is 3 hours.
From 12:15 pm to 1:15 pm is 1 hour.
Total duration = 3 hours + 1 hour = 4 hours.

The journey took $\boxed{\text{4 hours}}$ .

Solve the following problems: Calculate profit from cost and selling price, solve for y in an algebraic equation, and calculate journey duration.
