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
