Answer 2

Answer:

Given :-

• A car travels 85 meters in 5 seconds.

To Find :-

• What is the average speed ?

Solution :-

Given :

• Total Distance = 85 m
• Total Time = 5 seconds

According to the question by using the formula we get,

$\small \implies \sf\boxed{\bold{Average\: Speed =\: \dfrac{Total\: Distance}{Total\: Time}}}$

$\implies \sf Average\: Speed =\: \dfrac{85}{5}$

$\implies \sf Average\: Speed =\: \dfrac{17}{1}$

$\implies \sf\bold{\underline{Average\: Speed =\: 17\: m/s}}$

$\therefore$ The average speed is 17 m/s .

Hence, the correct options is option no (a) 17 m/s .
