Answer 1

$\huge\underline\blue{\textbf{Required Answer :-}}$

$\huge\underline\purple{\textbf{Given :-}}$

${\texttt{Distance travelled, d = 24.6 km}}$

${\texttt{Time, t = 30 minutes}}$

${\texttt{Time, t (in hrs) = 0.5 hrs}}$

$\huge\underline\pink{\textbf{To find :-}}$

${\texttt{Speed of helicopter to cover 24.6 km in 1800 sec.s}}$

$\huge\underline\green{\textbf{Solution :-}}$

${\texttt{We know that,}}$

${\texttt{Speed = Distance / Time}}$

: ⟹ ${\texttt{Speed of the helicopter, s =}}$ $\frac{24.6}{0.5}$

: ⟹ ${\texttt{s = 49.2 km/h}}$

${\texttt{Therefore, the required speed is}}$ $\underline\green{\textbf{49.2 km/h or 49200 m/s.}}$
