Correct Answer: 8
Solution :
Length of circular race = 1.2 km = 1200 m
The speeds of Zeenat and Nasreen are 18 km/hr and 27 km/hr respectively.
Relative speed of both in same direction = 27 – 18 = 9 km/hr = $9×\frac{5}{18}$ = 2.5 m/s
So, time taken = $\frac{1200}{2.5}=480\ s=8$ minutes
Hence, the correct answer is 8.
