Answer:

A.

Step-by-step explanation:

Answer:

[tex] \huge \: \boxed { \boxed{ \red{ a)t = \frac{d}{r}}}}[/tex]

Step-by-step explanation:

to understand this

you need to know about:

  • equation
  • PEMDAS

given:

  • [tex]d = rt[/tex]

to find

  • [tex]t[/tex]

let's solve:

[tex]step - 1 :define[/tex]

[tex]d = rt[/tex]

[tex]step - 2 : solve[/tex]

  1. [tex]rewrite : \\ rt = d[/tex]
  2. [tex]divide \: both \: sides \: by \: r : \\ \frac{rt}{r} = \frac{d}{r} [/tex]
  3. [tex]simplify : \\ t = \frac{d}{r} [/tex]

[tex] \huge \: \boxed { \boxed{ \red{ \therefore t = \frac{d}{r}}}}[/tex]
