Polly's Speedy Adventure: Calculating Miles Per Minute

In this article, we will delve into the world of mathematics, specifically focusing on calculating speed in miles per minute. We will use a real-life scenario to demonstrate how to calculate speed, making it easier to understand and apply the concept.

Polly travels to the park, which is 8 miles away, and it takes her 16 minutes to get there. Paige wants to know her speed in miles per minute. To calculate Polly's speed, we need to use the formula: speed = distance / time.

To calculate Polly's speed, we need to divide the distance she traveled (8 miles) by the time it took her to travel that distance (16 minutes).

Speed Formula

Speed = Distance / Time

In this case, the distance is 8 miles, and the time is 16 minutes. We can plug these values into the formula:

Speed = 8 miles / 16 minutes

Simplifying the Fraction

To simplify the fraction, we need to find the greatest common divisor (GCD) of 8 and 16. The GCD of 8 and 16 is 8. We can divide both the numerator and the denominator by 8 to simplify the fraction:

Speed = (8 miles) / (16 minutes) = (1 mile) / (2 minutes)

Representing the Speed as a Fraction

The speed can be represented as a fraction: 1/2 miles per minute.

In conclusion, Polly's speed in miles per minute is 1/2. This means that she travels 1 mile in 2 minutes. We can use this formula to calculate speed in any situation where we know the distance and time.

The fraction that represents Paige's speed in miles per minute is 1/2.
The correct answer is 1/2.

Let's consider a few more examples to reinforce the concept of calculating speed in miles per minute.

If it takes 20 minutes to travel 10 miles, what is the speed in miles per minute?
If it takes 30 minutes to travel 15 miles, what is the speed in miles per minute?

Solution to the First Example

To calculate the speed, we need to divide the distance (10 miles) by the time (20 minutes):

Speed = 10 miles / 20 minutes = 1/2 miles per minute

Solution to the Second Example

To calculate the speed, we need to divide the distance (15 miles) by the time (30 minutes):

Speed = 15 miles / 30 minutes = 1/2 miles per minute

In conclusion, calculating speed in miles per minute is a simple process that involves dividing the distance by the time. We can use this formula to calculate speed in any situation where we know the distance and time.
Polly's Speedy Adventure: Q&A

In our previous article, we explored the concept of calculating speed in miles per minute using a real-life scenario. We calculated Polly's speed in miles per minute and simplified the fraction to represent her speed. In this article, we will answer some frequently asked questions related to calculating speed in miles per minute.

Q1: What is the formula to calculate speed in miles per minute?

A1: The formula to calculate speed in miles per minute is: Speed = Distance / Time.

Q2: How do I simplify a fraction to represent speed in miles per minute?

A2: To simplify a fraction, you need to find the greatest common divisor (GCD) of the numerator and the denominator. Divide both the numerator and the denominator by the GCD to simplify the fraction.

Q3: What is the speed in miles per minute if it takes 20 minutes to travel 10 miles?

A3: To calculate the speed, divide the distance (10 miles) by the time (20 minutes): Speed = 10 miles / 20 minutes = 1/2 miles per minute.

Q4: What is the speed in miles per minute if it takes 30 minutes to travel 15 miles?

A4: To calculate the speed, divide the distance (15 miles) by the time (30 minutes): Speed = 15 miles / 30 minutes = 1/2 miles per minute.

Q5: Can I use this formula to calculate speed in other units, such as kilometers per hour?

A5: Yes, you can use this formula to calculate speed in other units, such as kilometers per hour. Simply convert the distance and time to the desired units and plug them into the formula.

Q6: What is the speed in kilometers per hour if it takes 1 hour to travel 5 kilometers?

A6: To calculate the speed, divide the distance (5 kilometers) by the time (1 hour): Speed = 5 kilometers / 1 hour = 5 kilometers per hour.

Q7: Can I use this formula to calculate speed in other situations, such as walking or running?

A7: Yes, you can use this formula to calculate speed in other situations, such as walking or running. Simply measure the distance and time, and plug them into the formula.

Q8: What is the speed in miles per minute if it takes 10 minutes to travel 2 miles?

A8: To calculate the speed, divide the distance (2 miles) by the time (10 minutes): Speed = 2 miles / 10 minutes = 1/5 miles per minute.
