Molly And Arthur Are Taking Their Daughter Ginny On A Roller Coaster Ride. For Safety Reasons, They Need To Find Their Total Weight Before Getting Into The Same Car. Molly's Weight Is $M$ Kilograms, Arthur's Weight Is $A$
Introduction
Roller coasters are a thrilling way to experience the rush of adrenaline and the beauty of engineering. However, before you can enjoy the ride, you need to ensure that you and your loved ones are safe. One crucial aspect of safety is knowing your total weight, especially when sharing a car with others. In this article, we will explore how Molly and Arthur can calculate their total weight before getting on the roller coaster with their daughter Ginny.
The Problem
Molly's weight is $M$ kilograms, and Arthur's weight is $A$ kilograms. To find their total weight, they need to add their individual weights together. This is a simple arithmetic operation that can be represented by the equation:
Why is Total Weight Important?
Knowing your total weight is essential for safety reasons, especially when sharing a car with others. Roller coasters have weight limits to ensure that the car can safely carry the passengers. If the total weight exceeds the limit, it can lead to accidents and injuries. By calculating their total weight, Molly and Arthur can ensure that they are within the safe weight limit and can enjoy the ride with their daughter Ginny.
Calculating Total Weight
To calculate their total weight, Molly and Arthur need to add their individual weights together. This can be done using a simple arithmetic operation:
For example, if Molly's weight is 50 kilograms and Arthur's weight is 70 kilograms, their total weight would be:
Real-World Applications
Calculating total weight is not limited to roller coasters. It is an essential aspect of many real-world applications, such as:
- Space Exploration: Astronauts need to calculate their total weight to ensure that they are within the safe weight limit for space travel.
- Medical Procedures: Medical professionals need to calculate the total weight of patients to ensure that they are within the safe weight limit for certain medical procedures.
- Industrial Settings: Industrial workers need to calculate their total weight to ensure that they are within the safe weight limit for certain tasks.
Conclusion
In conclusion, calculating total weight is an essential aspect of safety, especially when sharing a car with others. By using simple arithmetic operations, Molly and Arthur can ensure that they are within the safe weight limit and can enjoy the roller coaster ride with their daughter Ginny. This article has demonstrated the importance of calculating total weight and has provided a real-world example of how it can be applied.
