v=30km/ ч t=4ч

To find the distance traveled, you can use the formula:

\[ \text{Distance} = \text{Speed} \times \text{Time} \]

Here, the speed \( v \) is given as 30 km/h and the time \( t \) is 4 hours.

Substituting the values:

\[ \text{Distance} = 30 \text{ km/h} \times 4 \text{ h} = 120 \text{ km} \]

So, the distance traveled is 120 kilometers.
