allery12 km/h पर एक साइकिल चालक को 2 h लीड मिलती है। एक बाइक 18 km/h की गति से चलती है। पकड़ने का समय?
A3 घंटे
B4 घंटे
C6 घंटे
D2 घंटे
Answer & Solution
Correct answer: B. 4 घंटे
साइकिल चालक की बढ़त 12 × 2 = 24 किमी है और बाइक प्रति घंटे 18 − 12 = 6 किमी की बढ़त हासिल करती है, 24 ÷ 6 = 4 घंटे में पकड़ लेती है।
