Understanding the Problem

To solve this problem, we need to first understand the concept of average speed. Average speed is defined as the total distance traveled divided by the total time taken. In this case, the car travels 60 km in 36 minutes, and we need to find out how far it will travel in 1 hour and 12 minutes at the same average speed.

Calculating the Average Speed

To calculate the average speed, we need to convert the time from minutes to hours. There are 60 minutes in 1 hour, so 36 minutes is equal to 36/60 = 0.6 hours. Now, we can calculate the average speed using the formula:

Average Speed = Total Distance / Total Time

Plugging in the values, we get:

Average Speed = 60 km / 0.6 hours = 100 km/h

Converting Time to Hours

Now that we have the average speed, we need to convert the time from 1 hour and 12 minutes to just hours. There are 60 minutes in 1 hour, so 12 minutes is equal to 12/60 = 0.2 hours. Adding this to 1 hour, we get:

1 hour + 0.2 hours = 1.2 hours

Calculating the Distance Traveled

Now that we have the average speed and the time, we can calculate the distance traveled using the formula:

Distance = Average Speed x Time

Plugging in the values, we get:

Distance = 100 km/h x 1.2 hours = 120 km

Conclusion

Therefore, at the same average speed, the car will travel 120 km in 1 hour and 12 minutes.

Real-World Applications

This problem has many real-world applications, such as:

Traffic planning: Understanding the average speed of a car can help traffic planners to design more efficient routes and reduce congestion.
Fuel efficiency: Knowing the average speed of a car can help drivers to optimize their fuel consumption and reduce their carbon footprint.
Emergency services: Emergency services, such as ambulances and fire trucks, need to know the average speed of their vehicles to respond quickly and efficiently to emergencies.

Tips and Tricks

Here are some tips and tricks to help you solve this problem:

Use the formula: The formula for average speed is Distance / Time. Make sure to use this formula to calculate the average speed.
Convert time to hours: Make sure to convert the time from minutes to hours before calculating the average speed.
Use a calculator: If you're not comfortable with calculations, use a calculator to help you solve the problem.

A car travels 80 km in 45 minutes. At the same average speed, how far will it travel in 1 hour and 30 minutes?
A bike travels 20 km in 30 minutes. At the same average speed, how far will it travel in 1 hour and 15 minutes?
A train travels 120 km in 2 hours. At the same average speed, how far will it travel in 3 hours?

Conclusion

In conclusion, this problem is a great example of how to calculate the distance traveled at a given average speed. By using the formula and converting the time to hours, we can easily calculate the distance traveled. This problem has many real-world applications, and by practicing solving this type of problem, you can improve your math skills and become more confident in your ability to solve problems.

Q: What is the average speed of the car?

A: To calculate the average speed, we need to divide the total distance traveled by the total time taken. In this case, the car travels 60 km in 36 minutes. First, we need to convert the time from minutes to hours. There are 60 minutes in 1 hour, so 36 minutes is equal to 36/60 = 0.6 hours. Now, we can calculate the average speed using the formula:

Average Speed = Total Distance / Total Time

Plugging in the values, we get:

Average Speed = 60 km / 0.6 hours = 100 km/h

Q: How do I convert time from minutes to hours?

A: To convert time from minutes to hours, you need to divide the number of minutes by 60. For example, if you have 36 minutes, you can convert it to hours by dividing 36 by 60, which equals 0.6 hours.

Q: What is the distance traveled in 1 hour and 12 minutes?

A: Now that we have the average speed, we need to convert the time from 1 hour and 12 minutes to just hours. There are 60 minutes in 1 hour, so 12 minutes is equal to 12/60 = 0.2 hours. Adding this to 1 hour, we get:

1 hour + 0.2 hours = 1.2 hours

Now that we have the average speed and the time, we can calculate the distance traveled using the formula:

Distance = Average Speed x Time

Plugging in the values, we get:

Distance = 100 km/h x 1.2 hours = 120 km
