Pujari's Speed and Time Calculation: How Long Does It Take to Cover 1500 Meters?

Understanding how to calculate speed and the time it takes to cover a certain distance is a fundamental concept in both mathematics and sports. In this article, we will explore the scenario involving Pujari, who runs at a speed of 60 km/hr, and determine how long it takes her to cover a distance of 1500 meters. We will also provide a detailed step-by-step solution to this problem using both approaches for clarity.

How to Calculate Time with Speed and Distance

The fundamental formula for calculating time when you know the speed and distance is:

Time Distance / Speed

Let's break down the problem and solve it using this formula.

Method 1: Simplified Method

Given that Pujari's speed is 60 km/hr, we can first convert the speed into meters per second (m/s).

1 km/hr 1000 meters / 3600 seconds 5/18 m/s

Therefore, 60 km/hr 60 * (5/18) m/s 50/3 m/s

Now, we have the speed in meters per second.

Given the distance to cover is 1500 meters, we can use the formula:

Time Distance / Speed

Substituting the values:

T 1500 / (50/3) seconds

Calculation:

T 1500 * (3/50) seconds

T 90 seconds

Method 2: Quick Conversion Method

A simpler way to approach this problem is to convert the speed directly into meters per minute, and then calculate the time required for the given distance.

60 km/hr 60 * 1000 meters per hour 60000 meters per hour

1 hour 60 minutes, so 60000 meters per hour 1000 meters per minute

Given the distance to cover is 1500 meters, we can calculate the time required as follows:

Time 1500 meters / 1000 meters per minute 1.5 minutes

1.5 minutes 90 seconds

Conclusion

Both methods yield the same result: Pujari will take 90 seconds to cover a distance of 1500 meters at a speed of 60 km/hr. This understanding is crucial in various fields, including sports science, engineering, and everyday calculations.
