4 0

Answer: d = 1/5t

Step-by-step explanation:

\\Since it is a direct variation , Let d represent the distance and t represent the time ,then

\\d ∝ t

\\introducing the proportionality constant, we have

\\d = kt

\\Substituting t = 10 and d = 2 , we have

\\2 = 10k

\\k = 1/5

\\substitute k = 1/5 into the original equation , we have

\\d = 1/5t

Answer

-17


<u>Explanation</u>
