Final answer:
The speed of the automobile is 97 km/hr as given in the question. Other options provided (97 m/s, 97 miles/hr, and 97 ft/s) would be incorrect as they would require different conversion factors and calculations to convert from the given unit of km/hr.
Step-by-step explanation:
The speed of the automobile traveling at 97 km/hr is exactly that: 97 km/hr. When converting this speed into different units, it is important to use the correct conversion factors. For instance, 1 km/hr is not equivalent to 97 m/s. To convert kilometers per hour into meters per second, you divide the speed in km/hr by 3.6 (since 1 km = 1000 meters and 1 hour = 3600 seconds). Therefore, to convert 97 km/hr into meters per second, you would perform the calculation 97 ÷ 3.6, which does not equal 97. Similarly, to convert kilometers per hour into miles per hour, you would multiply by the conversion factor of 0.6214, which also would not yield 97. The same logic applies for converting to feet per second, taking into account that 1 meter equals 3.281 feet. So, of the options presented, the only correct answer is option 1): 97 km/hr.
