Question

Hello user
_______________________________

Can we write

$Speed \: = \frac{time \: }{distance}$
instead of writing it standard form

$Speed \: = \frac{distance \: }{time}$
if so ? then why ? if no Then ? then why ?

justify it

Answer 1

Nice question
Personally \times symbol used in three different occasions the cross product –vector product– (e.g.,).So it means it is same,multiplication.The used symbol depends on location.

Answer 2

hey mate !!!


here is your answer!!!


Speed = distance / time

or ,

1/ speed = time / distance .



here , we can't write ,

speed = time / distance
because


speed :-
speeds denotes the distance travel by a body in unit time .
➡ speed is a scaler quantity .

➡ it's SI unit is (m/ s ) .
-----------------------------------

let me elaborate more :-

Distance :-

the actual length of the path travelled by a moving body in any direction is known as distance .

➡ it is scaler quantity .


➡ it's SI unit is m .
_______________

time ( respect to speed and distance ) :-

time is division of distance / speed


it's SI unit is S .

BECAUSE ,

distance. / speed



=> m / m/s

=> second



============================


hence , Speed = Distance / time


or speed = m / s


we can also write

1/ speed = time / distance .

but we can't write

speed = Distance / time .


if we write so , than we have to take receprocal of speed .



hope it helps you dear !!!

thanks !!
