A motorist started a journey at 8:30 am, travelling at 120 km/hr and covered a distance of 240 km. Calculate the time taken and finish time. Given that a=4, b=2 and c=3. Find the value of abc and ac/b

The time he took is $\boxed{\text{2 hours}}$.

He finished the journey at $\boxed{\text{10:30 am}}$.

24. Given that $a=4$, $b=2$ and $c=3$. Find the value of:

The value of $abc$ is $\boxed{24}$.

The value of $\frac{ac}{b}$ is $\boxed{6}$.

The value of $a^2$ is $\boxed{16}$.

25. The sum of three consecutive odd numbers is 39. Find the numbers.

The next consecutive odd number is $x+2$.
The third consecutive odd number is $x+4$.

First number: $x = 11$
Second number: $x+2 = 11+2 = 13$
Third number: $x+4 = 11+4 = 15$
The three consecutive odd numbers are $\boxed{11, 13, 15}$.
