Question

Nancy and Diego are building model airplanes. Nancy has already built 5 model airplanes and Diego has built 0 model airplanes. Nancy can build 1 model airplane in an hour. Diego can build 2 model airplanes in an hour. How many hours will it take for Nancy and Diego to have an equal number of airplanes built if they both work non-stop?

Answer 1

5 hours

because Diego builds 2 per hour so 5 x 2 = 10 and navy does 1 per hour but has already built 5 so she also builds 10

Answer 2

The number of hours for Nancy and Diego to have an equal number of airplanes built if they both work non-stop will be 5.

What is the linear system?

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

Nancy and Diego are building model airplanes.

Nancy has already built 5 model airplanes and Diego has built 0 model airplanes.

Nancy can build 1 model airplane in an hour.

Diego can build 2 model airplanes in an hour.

Let x be the number of hours and y be the number of the model airplane.

Then the equation will be

y = x + 5      ...1

y = 2x          ...2

Then the number of the hours for Nancy and Diego to have an equal number of airplanes built if they both work non-stop will be

By solving the equations 1 and 2, then we have

2x = x + 5

 x = 5
