A running man crosses a bridge of length 500 meters in 4 minutes. At what…

Step-by-Step Solution

To calculate the man's speed in km/hr, follow these steps to ensure all units are consistent:

1. Identify the given values:

   • Distance = 500 meters

   • Time = 4 minutes

2. Convert units to the required format (km/hr):

   • Convert distance to kilometers: 500 meters = 500 / 1000 = 0.5 km.

   • Convert time to hours: 4 minutes = 4 / 60 = 1/15 hours.

3. Calculate speed:

   • Speed = Distance / Time

   • Speed = 0.5 / (1/15)

   • Speed = 0.5 * 15 = 7.5 km/hr.
