Best answer
Correct Answer - Option 1 : 6 km

GIVEN:

Raj covers the same distances with a speed of 2 kmph, 4 kmph, and 8 kmph. He takes 105 min for a whole journey.

FORMULA USED:

Speed = Distance/Time

CALCULATION:

Suppose distances are of ‘x’ km.

So,

x/2 + x/4 + x/8 = 105/60

⇒ 7x/8 = 105/60

⇒ x = 2

Hence, total distance = 3x = 6 km
