In question, We are given the values of time taken and speed of the cycle to reach from ramesh home to market. To find the distance between the ramesh house and market, we have to multiply speed with the time.
To calculate :
The distance between his house and market = ?
Solution :
To find the distance = ?
We know that,
\quad \red{\underline{\boxed{\sf Distance \ = \ Speed \times Time}}}
Distance = Speed×Time
Put the given values in the above formula.
\implies \sf Distance \ = \ 4 \times 15⟹Distance = 4×15
\implies \sf Distance \ = \ 60 \ meters.⟹Distance = 60 meters.
\begin{gathered} \\ \end{gathered}
Now,
Converting meter into kilometres,
\implies \sf 60 \times 60 \ = \ 3600 km⟹60×60 = 3600km
\implies \sf \dfrac {3600}{1000}⟹
1000
3600
\implies \sf 3.6 \ km⟹3.6 km
\begin{gathered} \\ \end{gathered}
