Final answer:
The car travels approximately 0.9 km in half a minute.
Step-by-step explanation:
The car is traveling at a uniform velocity of 108 km/h. To find the distance it travels in half a minute, we need to convert half a minute to hours. There are 60 minutes in an hour, so half a minute is equal to 0.5/60 = 0.00833 hours. The distance traveled can be calculated using the formula: speed = distance/time. Rearranging the formula, we have distance = speed * time. Substituting the given values, distance = 108 km/h * 0.00833 hours = 0.89964 km. First, we need to convert the velocity from km/h to m/s: 108 km/h = 30 m/s (since 1 km/h is approximately 0.27778 m/s). Then, we convert the time from minutes to seconds: 0.5 minutes = 30 seconds.
Now, we can calculate the distance: x = (30 m/s) × (30 s) = 900 meters. Therefore, the car travels 900 meters in half a minute.
