Solve the following arithmetic problems: 1.1 28694 428, 1.2 187296 / 4, 1.3 46514 / 17, 1.4 563 18 - 4, 1.5 Divide R350 in the ratio 3:4.

The product is $\boxed{\text{12280352}}$.

The quotient is $\boxed{\text{46824}}$.

The quotient is approximately $\boxed{\text{2736.12}}$.

The result is $\boxed{\text{10130}}$.

Total parts $= 3 + 4 = 7$

Value of one part $= \frac{\text{R}350}{7} = \text{R}50$

Kenzie's share $= 3 \times \text{R}50 = \text{R}150$

Connor's share $= 4 \times \text{R}50 = \text{R}200$
Kenzie gets $\boxed{\text{R150}}$ and Connor gets $\boxed{\text{R200}}$.

Given: Speed $= 60 \text{ km/hour}$, Time $= 8 \text{ hours}$.
Formula: Distance = Speed $\times$ Time.

We can travel $\boxed{\text{480 km}}$.

Given: Distance $= 480 \text{ km}$, Time $= 4 \text{ hours}$.
Formula: Speed = Distance $\div$ Time.

We are driving at a speed of $\boxed{\text{120 km/hour}}$.

The prime factorization of 24 is $\boxed{2^3 \times 3}$.
