Combine the common factors.
11x + 5 = 180
Subtract 5 from both sides.
11x = 175
Divide 11 from both sides to isolate the x.
x = 15.90909091
Upstream: 14 - 4 = 10. Miles per hour.
16 miles = 1.6 hours.
Downstream: 14 + 4 = 18.
16 miles = 16/18 = 8/9 or 0.888 of an hour.
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
