A man walking at the rate of 6 km/hr crosses a bridge in 15 minutes. The length of the bridge is ______.	Pick:
A) 1000 m
B) 1250 m
C) 1500 m
D) 1800 m
E) 2300 m
Hint: To find the answer in meter, we will first convert distance from km/hour to meter/sec by multiplying it with 5/18 .Also, change 15 minutes to seconds by multiplying it with 60.   Distance = Speed x Time   1. Convert speed into m/sec:   6 x	5 / 18 m/s = 1.66 m/s   2. Convert time from minutes into seconds = 15 x 60 s = 900 sec   3. 1500 malculate : Distance = 1.66 x 900 = 1500 m   ANSWER IS 1500 m
