Francesca is growing 1/2 inch in each year. How many years will it take for her to grow 6 inches

The number of years it will take for Francesca to grow 6 inches is 12 years

Step-by-step explanation:

The height to which Francesca is growing, Δh/Δt = 1/2 inch per year

The number of years, 'Δt', it will take her to grow 6 inches given as follows;

Δh/Δt = 1/2 inch/year

Δh = 1/2 inch/year × Δt

When Francesca grows 6 inches, we have;

Δh = 6 inches

∴  Δh = 6 inches = 1/2 inch/year × Δt

6 inches = 1/2 inch/year × Δt

Δt = 6 inches/(1/2 inch/year) = 12 years

The number of years it will take for Francesca to grow 6 inches, Δt = 12 years
