Answer:
40 MPH (Miles Per Hour)
Step-by-step explanation:
Well i will put it in simple terms. Put 2/3 into a decimal point, which for this fraction is 0.66666666667 (the 6 is infinite basically). Then you multiply it by 60, because you know it goes in that distance in one minute and 60 minutes makes a hour, which equals 40. So the answer is 40 MPH.
If i remember correctly i think you just cross multiply <span />
The given equation is:

We need to find which set of parametric equations, result in the equation given above. The correct answer is option A.

From first equation, we can write t =x/5. Using this value in second equation, we get:

Thus the set of equations in option A result in the given relation.
So, the answer to this question is option A
Some textbooks describe direct variation by saying " y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x . ") This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.
