67. The formula to calculate a rate is r =

Which of the following is a equivalent formula?
c) d =
a) d = r *t
b) d = r +t
d) none of the above

Answer 1

a) d = r *t

Step-by-step explanation:

The equivalent formula for calculating rate is given as:

d = r *t

Where d is the amount of substance, r is the rate and t is the time taken.

The rate of process is the amount or quantity attained per unit of time.

It is usually expressed as;

r =
`(d)/(t)`

So, the other variant will be d = r *t
