A man walking at the rate of 5 km/hr crosses a bridge in 15 minutes. The length of the bridge (in meters) is-
- A. 600
- B. 600
- C. 600
- D. 600
Answer: Option D
Explanation:
Rate for walking per minute = (5×1000)/60 meter = 250/3 meter
In 1 minute he crosses 250/3 meter
In 15 minute he crosses 250/3 meter
15 minute he crosses = (250×15)/3 = 1250 meter
So, the length of the bridge is 1250 meter.
