Question

On one side of a 1.2 km long garden path, 61 trees are planted at equal intervals. What is the total distance between 6 consecutive trees?
(a) 115
(b) 105
(c) 110
(d) 100

ONLiNE UPSC · Accepted Answer

Total length = 1.2 km = 1200 meters
Number of trees = 61 &rarr; Number of gaps = 60
Distance between each pair = 1200/60 = 20 meters
Distance between 6 consecutive trees = 5 gaps
Total = 5 &times; 20 = 100 meters
Hence, option d is correct.
