allery180 کلومیٹر کے سفر میں 3.5 گھنٹے لگتے ہیں: 30 کلومیٹر فی گھنٹہ کی رفتار سے 60 کلومیٹر، 60 کلومیٹر فی گھنٹہ کی رفتار سے 60 کلومیٹر۔ آخری رفتار؟
A150 km/h
B120 km/h
C90 km/h
D100 km/h
Answer & Solution
Correct answer: B. 120 km/h
پہلے دو مراحل میں 2 + 1 = 3 گھنٹے لگتے ہیں، 60 ÷ 0.5 = 120 km/h پر 60 km کے لیے 0.5 گھنٹے چھوڑتے ہیں۔
