Respuesta :
Sarah and Andy will take 28 minutes to pick a bushel of apple together.
Rational Equations:
A rational equation is an equation containing at least one fraction whose numerator and denominator are polynomials.
According to the given sum,
Time taken by Sarah = 45 minutes
Time taken by Andy = 75 minutes
Time taken by them when they are working together:
⇒ [tex]\frac{1}{45}[/tex] + [tex]\frac{1}{75}[/tex] = [tex]\frac{1}{t}[/tex]
⇒ [tex]\frac{5 + 3}{225}[/tex] = [tex]\frac{1}{t}[/tex]
⇒ [tex]\frac{8}{225}[/tex] = [tex]\frac{1}{t}[/tex]
⇒ [tex]t = \frac{225}{8}[/tex]
⇒ t = 28 minutes
Hence, we can conclude that While working together, Sarah and Andy will take 28 minutes to complete picking up bushel of apples.
