To find the distance traveled by the lorry, we can use the formula:
\[
\text{Distance} = \text{Speed} \times \text{Time}
\]
1. Convert the time from minutes to hours. Since 45 minutes is equal to \( \frac{45}{60} = 0.75 \) hours.
2. The speed of the lorry is 30 kilometers per hour.
Now, we can calculate the distance:
\[
\text{Distance} = 30 \text{ km/h} \times 0.75 \text{ h} = 22.5 \text{ kilometers}
\]
Therefore, the journey is 22.5 kilometers long.
\[
\text{Distance} = \text{Speed} \times \text{Time}
\]
