A man walking at a speed of 5 km/h passes a bridge in 15 minutes. What is the length of the bridge (in meters) ? |
1000 1200 1250 1500 |
1250 |
Formula used here is :- Speed = \(\frac{Distance}{Time}\) 5 km = \(\frac{Distance}{15 min }\) 5000 × \(\frac{15}{60 }\) = Distance Distance = 1250 m So, length of bridge ( in meter ) = 1250 m |
