To determine the total distance the boy has walked, we need to analyze the distances between each pair of boys he meets. The arrangement of the boys is as follows: Nitin (N), Atul (A), Kunal (K), Dinesh (D), and Prashant (P)
Identify the distances between each pair of boys:
The distance from Nitin to Atul is given as NA = 25
The distance from Atul to Kunal is AK = 40
The distance from Kunal to Dinesh is KD = 60
The distance from Dinesh to Prashant is DP = 90
Calculate the total distance walked by summing all the individual distances:
Required distance = NA + AK + KD + DP
Substituting the values:
Required distance = 25m+40m+60m+90
Perform the addition:
Required distance = 25+40+60+90=215m
The correct option is (A): 215 metres
