Question

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?

Answer 1

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
