Given:

The total race was 1.2 km.

The speed of Zeenat is 18 km/h and The speed of Nasreen is  27 km/h.

Concept used:

Distance = Speed × time 

Relative speed in the same direction is the difference of their speed.

Calculation:  

Relative speed will be (27 - 18) km/h = 9 km/h

The relative distance is 1.2 km 

So the time will be,

⇒ (1.2 / 9) × 60 

⇒ 0.4 × 20 = 8 minutes

∴ The correct option is 4
