A person has to make a journey of 72 Kms. He rides a cycle at 12 Km/hr. After going certain distance, the cycle got punctured and he walks the remaining distance at \(  \Large 4\frac{1}{2} \)Km/hr. Where did the cycle got punctured if the total time taken for the journey was \(8 \frac{1}{2} \) hours?

A) 18 Kms
B) 54 Kms

C) 36 Kms
D) 48 Kms

Correct answer:
B) 54 Kms

Description for Correct answer:

\( \Large 8\frac{1}{2}\) = \( \Large \frac{x}{12} + \frac{72 - x}{4\frac{1}{2}}\)
X = 54 km
