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
