Solve V_{m}(t)=Deltas/Deltat=f(t+Deltat)-f(t)/Deltat

$$V _ { m } ( t ) = \frac { \Delta s } { \Delta t } = \frac { f ( t + \Delta t ) - f ( t ) } { \Delta t }$$

Solve for f

$$f=\frac{s}{t}$$

$$\Delta \neq 0\text{ and }t\neq 0$$

Steps for Solving Linear Equation

Multiply both sides of the equation by t\Delta .

$$\Delta s=f\left(t+\Delta t\right)-ft$$

Use the distributive property to multiply f by t+\Delta t.

$$\Delta s=ft+f\Delta t-ft$$

Combine ft and -ft to get 0.

$$\Delta s=f\Delta t$$

Swap sides so that all variable terms are on the left hand side.

$$f\Delta t=\Delta s$$

The equation is in standard form.

$$t\Delta f=s\Delta$$

Divide both sides by \Delta t.

$$\frac{t\Delta f}{t\Delta }=\frac{s\Delta }{t\Delta }$$

Dividing by \Delta t undoes the multiplication by \Delta t.

$$f=\frac{s\Delta }{t\Delta }$$

Divide \Delta s by \Delta t.

$$f=\frac{s}{t}$$

Solve for s

$$s=ft$$

$$\Delta \neq 0\text{ and }t\neq 0$$

Steps for Solving Linear Equation

Multiply both sides of the equation by t\Delta .

$$\Delta s=f\left(t+\Delta t\right)-ft$$

Use the distributive property to multiply f by t+\Delta t.

$$\Delta s=ft+f\Delta t-ft$$

Combine ft and -ft to get 0.

$$\Delta s=f\Delta t$$

The equation is in standard form.

$$\Delta s=ft\Delta$$

Divide both sides by \Delta .

$$\frac{\Delta s}{\Delta }=\frac{ft\Delta }{\Delta }$$

Dividing by \Delta undoes the multiplication by \Delta .

$$s=\frac{ft\Delta }{\Delta }$$

Divide f\Delta t by \Delta .

$$s=ft$$
