Does the speed of a planet remain constant in its orbit?

$A$ planet revolves around the Sun in an elliptical orbit,where the semi-major axis $a$ is double the semi-minor axis $b$ $(a = 2b)$. The Sun is at the focus. Given that the planet takes $24$ hours to travel through the path $bed$ as shown in the figure,find the time taken by the planet to travel along the path $dab$.

According to Kepler,planets move in

Kepler's second law regarding the constancy of areal velocity of a planet is a consequence of the law of conservation of
