To find out how far the car will travel, you can use the formula:
\[ \text{Distance} = \text{Speed} \times \text{Time} \]
Given that the speed of the car is 80 km/h and the time is 3 hours, you can plug these values into the formula:
\[ \text{Distance} = 80 , \text{km/h} \times 3 , \text{h} = 240 , \text{km} \]
Therefore, the car will travel 240 kilometers in 3 hours.
