Answer 1

$\huge{\star}{\underline{\boxed{\red{\sf{Answer :}}}}}{\star}$

Given :-

Time = 2hrs

Distance = 80 km/h

======================>

To Find :-

Speed in km/h and m/s

=========================>

Solution :-

We have formula :-

$\huge{\boxed{\boxed{\sf{Speed \: = \: {\frac{Distance}{Time}}}}}}$

______________[Put Values]

Speed = 80/2

Speed = 40

________________

In km\h :-

$\huge{\sf{Speed \: = \: 40kmh^{-1}}}$

============------------==============

In m\s

Multiply it by 5/18

Speed = 40 * 5 / 18

Speed = 11.11

$\huge{\sf{Speed \: = \: 11.11 \: ms^{-1}}}$
