A man driving a car at a speed of 54 km/hr crosses a bridge in 1.7 minutes. Find the length of the bridge.
एक व्यक्ति 54 किमी/घंटा की चाल से कार चलाकर एक पुल को 1.7 मिनट में पार करता है। पुल की लंबाई ज्ञात कीजिए।
Detailed Solution & Logic
Correct Answer:
1.53 km
Speed = 54 km/hr
Time = $1.7$ minutes $= \frac{1.7}{60}$ hours
Distance (length of bridge):
$= 54 \times \frac{1.7}{60}$
$= \frac{91.8}{60} = 1.53$ km
Correct Answer: 1.53 km
