Answer:

b. All positive  real numbers and zero

Step-by-step explanation:

We are given that  the distance traveled by a cyclist is given by

d(t)=5t

Where t=Time in seconds

We have to find the domain  of the function .

We know that distance is always positive.

Given function is linear function .

We know that domain of linear function is set of all real numbers.

But t is time and t is always positive.

Therefore, domain of function includes  all positive real numbers and zero.

Answer: b. All  positive real numbers and zero.
