what is the length of a bridge which a man running 15 km per hour can cross in 5 minutes

Dear Student,
Speed = 15km/h

Time needed = 5 mins

Convert the time to hour:

5 mins = 5/60 = 1/12 hour


Find the distance:

Distance = Speed x Time

Distance = 15 x 1/12 = 1.25 km


Answer: The bridge is 1.25 km long


Regards
