Will the body be travelling with a constant speed or a constant acceleration if the distance travelled by the body is directly proportional to time?

Respuesta :

distance ( d ) is proportional to time ( t ) 

d α t   ( You can remove the proportionality operator provided that you add a constant) 

so 

d = const x t
d/t = const

we know that 

d/t = v

so v = const

so constant speed
