Question

Solve for the rate in the eqution d=rt

Answer 1

The rate of the equation is r when r is a constant

Explanation:

We need to solve for the rate of the equation

d = rt

Differentiating on both sides with respect to time

`\frac{\mathrm{d} d}{\mathrm{d} t}` =
`\frac{\mathrm{d} rt}{\mathrm{d} t}`

Considering r as a constant

`\frac{\mathrm{d} d}{\mathrm{d} t}` = r×
`\frac{\mathrm{d} t}{\mathrm{d} t}`

where,
`\frac{\mathrm{d} t}{\mathrm{d} t}` = 1

`\frac{\mathrm{d} d}{\mathrm{d} t}` = r

The rate of the equation is r when r is a constant
