एक व्यक्ति 50 किमी/घंटा की गति से साइकिल चलाकर 39 मिनट में एक पुल पार करता है। पुल की लंबाई ज्ञात कीजिये?
Detailed Solution & Logic
Correct Answer:
32.5 km
$ \text{Distance} = \text{Speed} \times \text{Time} $
Speed of bicycle = 50 km/h
Time taken = 39 minutes =$ \frac{39}{60} $ hours = 0.65 hours
$ = 50 \times 0.65 $
Answer = 32.5 km
