Correct Option: B

AI Explanation

To solve this question, we can use the formula:

Time = Distance / Speed

Let's calculate the time taken in both scenarios:

Scenario 1: Walking at a speed of 10 km/hr Time taken = Distance / Speed Time taken = 10 km / 10 km/hr Time taken = 1 hour

However, we need to convert this time into minutes because the question asks for the answer in minutes. Since 1 hour is equal to 60 minutes, the time taken in minutes is:

Time taken = 1 hour * 60 minutes/hour Time taken = 60 minutes

Therefore, it takes the man 60 minutes to go to the market from home by walking.

Scenario 2: Riding a car at a speed of 20 km/hr Time taken = Distance / Speed Time taken = 10 km / 20 km/hr Time taken = 0.5 hour

Converting this time into minutes:

Time taken = 0.5 hour * 60 minutes/hour Time taken = 30 minutes

Therefore, it takes the man 30 minutes to go to the market from home by riding his car.

Comparing the two scenarios, we see that the man takes 60 minutes to walk and 30 minutes to ride his car. Therefore, the correct answer is option B) 10.
