$\rm{If \ a \ car \ attains \ a \ speed \ of \ 36 kmh(-1)}$

$\rm{from \ rest \ in \ 12 \ minutes, \ what \ is}$

$\rm{ the \ distance \ covered?}$

$\sf\large\underline\pink{Given:}$

$\rm{Car \ attains \ speed \ of \ 36 \ kmh^-1}$

$\rm{Time \ = \ 12 \ mins}$

_________________________________________

$\sf\large\underline\blue{To \ Find}$

$\rm{Distance \ covered \ by \ the \ car}$

$\green{\underline{\underline{\red{\boxed{\boxed{\purple{\star{\sf Solution:}}}}}}}}$

$\rm{Here,}$

$\rm{Initial \ velocity \ : 0}$

$\rm{Velocity \ changes \ to \ 36 \ kmh^-1}$

$\rm\therefore{V \ = \ 36 \ kmh-1}$

$\rm{Time(t) \ = \ 12 \ min}$

$\rm{ First \ convert \ velocity \ into \ ms^-1 \ and}$

$\rm{time \ into \ seconds}$

$\rm\therefore{ }$

$v = 36 \times \frac{3600}{60 \times 60}$

$\rm{Time \ = \ 12 \ min}$

$\rm\implies{Time \ = \ 12 \ \times 60 \ sec}$

$\rm\implies{Time(t) \ = \ 720 \ s}$

$\rm{We \ know,}$

$v = u + at$

$10 = 0 + a \times 720$

$a = \frac{10}{720} \: \frac{m}{ {s}^{ - 2} }$

$a = \frac{1}{72} \: \frac{m}{ {s}^{ - 2} }$

$\rm{We \ know,}$

$\rm{v^2 \ - \ u^2 \ = \ 2as}$

$\rm\implies{10^2 \ - \ 0 \ = \ 2 \times \frac{1}{72} \times s}$

$\rm\implies{100 \ = \ \frac{s}{36}}$

$\rm\implies{s \ = \ 36 \ times 100}$

$\rm\implies{s \ = \ 3600 \ m}$
