Answer 2

$\begin{gathered}\begin{gathered}\bf Given -  \begin{cases} &\sf{distance \: = 950 \: m} \\ &\sf{time \: = 5 \: minutes} \end{cases}\end{gathered}\end{gathered}$

$\begin{gathered}\begin{gathered}\bf  To \:  Find :-  \begin{cases} &\sf{speed \: in \: km \: per \: hour}  \end{cases}\end{gathered}\end{gathered}$

$\large\underline\purple{\bold{Solution :- }}$

$\tt \ \: :  ⟼ Distance = 950 \: m \: = \dfrac{950}{1000} = \dfrac{19}{20} km$

$\tt \ \: :  ⟼ Time = 5 \: min \: = \dfrac{5}{60} = \dfrac{1}{12} \: hour$

$\tt \ \: :  ⟼ We \: know, \: Speed = \dfrac{Distance}{Time}$

$\tt\implies \:Speed = \dfrac{19}{20} \div \dfrac{1}{12}$

$\tt\implies \:Speed = \dfrac{19}{20} \times 12$

$\tt\implies \:Speed \: = \: \dfrac{19}{10} \times 6$

$\tt\implies \:Speed = 11.4 \: km \: per \: hour$
