Calculating Distance Traveled by a Bus: A Step-by-Step Guide

Understanding how to calculate the distance traveled by a bus using its speed and travel time is a fundamental concept in basic mathematics. This guide will walk you through the process of calculating the distance a bus will cover in 20 minutes when traveling at a speed of 60 kilometers per hour (km/h). We will use the formula Distance Speed × Time, and also explore some alternative methods to perform the calculation.

Basis of the Calculation

The key formula used in this calculation is the distance formula:

Distance (d) Speed (s) × Time (t)

Example Scenario

A bus has a speed of 60 km/h. How much distance will it travel in 20 minutes?

Step-by-Step Calculation

Method 1: Direct Substitution

Firstly, convert the time from minutes to hours, as the speed is given in km/h.

20 minutes 20/60 hours 1/3 hours

Now, plug the values into the distance formula:

Distance 60 km/h × 1/3 h 20 km

Method 2: Simplified Units Conversion

Another approach is to use unit conversions directly within the formula:

20 min 20 minutes × 1 hour/60 minutes 1/3 hour

Speed 60 km/h, Time 1/3 hour

Distance 60 km/h × 1/3 hour 20 km

Method 3: Using d vt

Here, d represents distance, v represents velocity, and t represents time. Converting the time from minutes to hours directly in the formula:

v 60 km/h, t 20/60 1/3 hours

d 60 km/h × 1/3 hours 20 km

Alternative Calculation: Detailed Explanation

Some may find it a bit challenging to perform these calculations, but understanding the underlying principles can make it easier:

Step 1: Convert Time to Hours

Time 20 minutes 20/60 hours 1/3 hours

Step 2: Identify Speed and Time in the Formula

Speed 60 km/h, Time 1/3 hours

Step 3: Use the Distance Formula

Distance Speed × Time 60 km/h × 1/3 hours 20 km

Conclusion

The bus will travel 20 kilometers in 20 minutes when traveling at a constant speed of 60 km/h. Understanding the steps involved in performing these calculations can be useful in various real-world scenarios, such as planning journeys or analyzing transportation data.
