37 trees are planted in a straight line such that distance between any two consecutive trees is same. A car takes 20 seconds to reach the 1…

Let the distance between 2 trees = a units

Then, the distance covered to reach 13th tree = 12a units

⇒ Time taken to cover a units = 20/12 = 1.67 sec

Remaining distance to be covered = 36a – 12a = 24a units

⇒ Time taken to cover 24a units = 24 × 1.67 = 40 sec

∴ the correct option is 2)
