Best answer
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
