Correct Answer - Option 3 : 6 km

**Given:**

Speeds = 20 km/h, 60 km/h, 4 km/h

Time = 38 minutes

**Formula used:**

Speed = distance/time

**Calculation:**

Let the equal distances be x km

A.T.Q

x/20 + x/60 + x/4 = 38/60

⇒ 3x/60 + x/60 + 15x/60 = 38/60

⇒ 19x = 38

⇒ x = 2km

∴ Total Distance = 2 + 2 + 2 = 6 km

**∴ The distance is 6 km**
