Respuesta :

The mass of the rider 1 is equal to 4 grams.

What is the mass of the missing rider?

In accordance with the statement, we know the mass of the entire system formed by three riders, of which the mass of two riders are known. The mass of the third rider can be calculated from the previous information:

m = m₁ + m₂ + m₃  

Where:

  • m₁ - Mass of rider 1.
  • m₂ - Mass of rider 2.
  • m₃ - Mass of rider 3.
  • m - Mass of the entire system.

m₁ = m - m₂ - m₃

m₁ = 694 g - 600 g - 90 g

m₁ = 4 g

The mass of the rider 1 is equal to 4 grams.
