Correct Answer - Option 3 : 6600 m

**Given:**

Speed on vehicle = 36 kmph,

time = 20 minutes = 1200 seconds

Total distance = 25% cycle + 20% bike + 55% rickshaw

**Formula used:**

Speed = Distance / time

1 kmph = 5/18 m/s

**Calculations:**

Calculating total distance first

⇒ Distance = speed × time

⇒ D = 36 × 5 × 1200 / 18

⇒ D = 12000 m

Now,

⇒ Total distance D = 0.25D + 0.20D + 0.55D

⇒ Distance covered in rickshaw = 0.55 × 12000

⇒ Distance covered in rickshaw = 6600 m

**∴**** Distance covered in rickshaw by student is 6600 m**
