A Running Man crosses a Bridge of Length 500 meters in 4 minutes. At what speed he is running?

To determine the speed at which a man is running based on the given information, you can use a basic mathematical approach.

A man crosses a bridge of length 500 meters in 4 minutes. We need to find his running speed in kilometers per hour (km/h).

The man covers 500 meters in 4 minutes. To find out how far he covers in 1 minute, divide the total distance by the total time

Distance per minute = 500/4 = 125 meters/minute

There are 60 minutes in an hour. To find the total distance covered in one hour, multiply the distance covered per minute by 60

Distance in one hour = 125 x 60 = 7500 meters

Since 1 kilometer equals 1000 meters, convert the distance covered in one hour into kilometers

Distance in kilometers = 7500/1000 = 7.5 kilometers

The distance covered in one hour is the speed of the man

Speed = 7.5 km/h

How to Determine Speed from Time and Distance?

In mathematics, calculating speed is a practical application of basic arithmetic. To determine the speed of an object or person based on the time taken and distance covered, follow these simple steps. When given the time it takes to travel a certain distance, you can calculate speed by using fundamental principles of distance, time, and speed relationships. Speed is defined as the rate at which an object covers distance over time. It is typically measured in units like meters per second (m/s) or kilometers per hour (km/h).

Calculation Process

• First, identify the total distance traveled. This could be in meters, kilometers, or any other unit of length.
• Next, note the total time taken to cover the distance. Time is usually recorded in minutes or hours.
• To find the distance covered per unit of time, divide the total distance by the total time. This gives the speed in units of distance per time, such as meters per minute or meters per hour.
• Often, the speed needs to be converted into a more standard unit, like kilometers per hour (km/h). Convert meters to kilometers and minutes to hours as required.
• Finally, the result from the above steps provides the speed of the object or person. This result tells you how fast the object is moving over a given period.

Applications

• Determining vehicle speed or travel time.
• Measuring athletes' performance, like a runner's speed.
• Estimating how quickly tasks or movements are completed.
