Answer

\text{12 km/h}

3 steps

Calculate the total time taken for the journey.
Kaari left at 8:00 a.m. and completed the journey at 10:00 a.m.
Time taken = 10:00 a.m. - 8:00 a.m. = 2 hours.
Use the formula for speed.
The formula for speed is:
$\text{Speed} = \frac{\text{Distance}}{\text{Time}}$
Given distance = 24 kilometres.
Given time = 2 hours.
Substitute the values into the formula and calculate the speed.
$\text{Speed} = \frac{24 \text{ km}}{2 \text{ hours}}$ $\text{Speed} = 12 \text{ km/h}$
The speed was 12 kilometres per hour.
$\text{12 km/h}$
