therefore it is 10 kmph

Answer 2

Step-by-step explanation:

⠀

$\underline{\bigstar\:\textsf{According to the given Question :}}$

$:\implies\sf Distance=Speed \times Time\\\\\\:\implies\sf (50 + 100) \:m = Speed \times 10 \:s\\\\\\:\implies\sf 150 \:m = Speed \times 10 \:s\\\\\\:\implies\sf \dfrac{150 \:m}{10 \:s} = Speed\\\\\\:\implies\sf Speed = 15 \:m/s\\\\\\:\implies\sf Speed = 15 \times \dfrac{18}{5}\:km/hr\\\\\\:\implies\sf Speed = 3 \times 18\:km/hr\\\\\\:\implies\underline{\boxed{\sf Speed = 54\:km/hr}}$

⠀

$\therefore\:\underline{\textsf{Speed of the container is C) \textbf{54 km/hr}}}.$
