Answer 2

First always, whenever you are doing a sum, write down all the information given for better understanding.

in this question, given,

Time taken for Vaani to reach her house after taking a round in the park = 20 minutes 30 seconds.

Time taken by Vaani to take a round in the park = 7 minutes 51 seconds.

Find the time taken by Vaani to walk from the park to her house.

for this, we just simply have to subtract time taken to take a round in the park from total time taken.

2O minutes 30 seconds - 7 minutes 51 seconds.

clearly we can convert both to seconds to get a better understanding.

1 minute = 60 seconds

20 minutes = 20 × 60 = 1200 seconds

7 minutes = 7 × 60 = 420 seconds

Time taken for Vaani to walk from the park to her house = (1200+30) - (420+51) = 1230 - 471 = 759 seconds

759 seconds = 12.65 minutes or 12 minutes 39 seconds

hope it helps

have a nice day!
