Question

The distance-time curve for a hypothetical journey has the shape of an equilateral triangle with one side along the time axis: the curve rises along one side of the triangle and returns to the axis along the other. Such a journey is:

TestHub · Accepted Answer

The second half of the triangle shows the distance decreasing as time increases. Total distance travelled is a non-decreasing quantity, so no real journey can produce this curve. (As a displacement-time graph the triangle would still need an instantaneous velocity reversal at the corner, i.e. an infinite acceleration, so a real curve would be rounded there.) Option B.
