A man is walking at the rate of 10 km/hr crosses a bridge in 15 minutes. The length of the bridge is
Choose the most appropriate option: A) 1000 meters B) 1050 meters C) 1200 meters D) 1250 meters E) 2500 meters

Rationale: "explanation : we need to get the answer in meters . so we will first of change distance from km / hour to meter / sec by multiplying it with 5 / 18 and also change 15 minutes to seconds by multiplying it with 60 . speed = 10 â ˆ — 5 / 18 = 25 / 9 m / sec time = 15 â ˆ — 60 seconds = 900 seconds distance = time â ˆ — speed / distance = 25 / 9 â ˆ — 900 = 2500 meter option e"
Answer: E
