The bowing of the Messenger of Allah ﷺ, and when he raised his head from bowing, and his prostration, and the time between the two prostration, were almost equal in length. (Using translation from Nasāʾī 1065)
أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ «رُكُوعُهُ إِذَا رَكَعَ وَإِذَا رَفَعَ رَأْسَهُ مِنَ الرُّكُوعِ وَسُجُودُهُ وَبَيْنَ السَّجْدَتَيْنِ قَرِيبًا مِنَ السَّوَاءِ»
