v2.c17.s8.8

"The daily travel [*S*] diminished by the march of the first day [*s*] is doubled; this is increased by the common increment [*b*]. That (sum) multiplied by itself is designated {as the *kṣepa* quantity}. The product of the daily travel and the start [t] being multiplied by eight times the common increment, the *kṣepa* quantity is added. The square-root of this {is increased by the *kṣepa* quantity; the sum divided by twice the common increment will give the required number of days}."
