Answer 2

Answer:

Given Information:-

• Distance covered by the car = 50 mtrs
• Time taken to cover 50 mtrs = 4 sec.s

To Find:-

• Speed in metres/second.

_______________...

We know,

$\boxed{Speed = \frac {Distance}{Time}}$

Hence, ACCORDING TO THE FORMULA,

_____...

$Speed = \frac{50 \ metres}{4 \ seconds}$

(Written an equation as per the formula given above)

$\implies \frac{50 \ metres}{4 \ seconds}$

$\implies \frac{\cancel{50 \ metres}}{\cancel{4 \ seconds}}$

(Cancelled 4 and 50 by taking common 2,

i.e.

• 2(25) = 50
• 2(2) = 4)

$\implies \frac{25 \ metres}{2 \ seconds}$

(After cancellation)

$\implies \frac{{\cancel{25}}}{\cancel{2}}$

(Again cancelled by taking common 2,

i.e.

• 2(12.5) = 25
• 2(1) = 2 )

$\implies \frac{12.5 \ metres}{second}$

(Result)

$\boxed{ \tt\green{12.5 \ metres \ per \ second} }$

_________...

REQUIRED ANSWER:-

$\therefore$ Speed of the car is 12 metres per second.
