Option 1: 220
Option 2: 215
Option 3: 210
Option 4: 225
Correct Answer: 225
Solution :
Given: Speed of Sohan = 36 km/h
Speed of Amit = 54 km/h
Length of circular track = 1125 m
Relative speed of Sohan and Amit (same direction) = 54 – 36 = 18 km/h
18 km/h = 18 ×
Time taken by them to meet for the first time =
Hence, the correct answer is 225.
