alleryఒక వాహనం 10 km రోడ్డులో ఐదింట రెండు వంతుల దూరాన్ని 20 km/h వేగంతో మరియు మిగిలిన దూరాన్ని 30 km/h వేగంతో ప్రయాణిస్తుంది. సగటు వేగం ఎంత?
A25 km/h
B26 km/h
C28 km/h
D24 km/h
Answer & Solution
Correct answer: A. 25 km/h
20 వేగంతో 4 km కు 0.2 h మరియు 30 వేగంతో 6 km కు 0.2 h పడుతుంది, కాబట్టి 0.4 h లో 10 km అంటే 25 km/h.
