The total time taken by the object to travel from A to B can be found by adding the time taken in each region. Since the speed in region I is 100 m/s and in region II is 71 m/s, we need to know the distances covered in each region to calculate the time. However, the distances are not provided directly in the question. Assuming the distances in each region are known or can be calculated based on additional information (which might be missing from the question as presented), the time for each region is calculated by dividing the distance by the speed in that region. The total time is the sum of these individual times. Without specific distances, we cannot calculate the exact times, but the correct answer would involve understanding this principle of dividing the distance by the speed to find time and then summing these times. Since the specific choice is selected without the detailed calculation shown here, it suggests there might be additional information or context provided elsewhere in the original problem setup that leads to the selection of choice B (60.8 ms) as the correct answer.
