Problem Statement
A 150 m train runs at 36 km/h and overtakes a man walking at 3 km/h in the same direction. How long will it take to pass him completely?
Explanation
Relative speed is thirty six minus three equals thirty three km per hour. Convert to meters per second for length coverage. Thirty three times five over eighteen equals nine point one six seven. Time equals one hundred fifty divided by nine point one six seven which is about sixteen point four seconds.
