Based on this passage, how many miles did Gorbachev walk each week for his round trip commute to school?

Context: The village school was closed during much of the war but re-opened in autumn 1944. Gorbachev did not want to return but when he did he excelled academically. He read voraciously, moving from the Western novels of Thomas Mayne Reid to the works of Vissarion Belinsky, Alexander Pushkin, Nikolai Gogol, and Mikhail Lermontov. In 1946, he joined the Komsomol, the Soviet political youth organization, becoming leader of his local group and then being elected to the Komsomol committee for the district. From primary school he moved to the high school in Molotovskoye; he stayed there during the week while walking the 19 km home during weekends. As well as being a member of the school's drama society, he organized sporting and social activities and led the school's morning exercise class. Over the course of five consecutive summers from 1946 onward he returned home to assist his father in operating a combine harvester, during which they sometimes worked 20-hour days. In 1948, they harvested over 8,000 centners of grain, a feat for which Sergey was awarded the Order of Lenin and his son the Order of the Red Banner of Labour.

Answer: According to this passage, Gorbachev's round trip walking commute to school was 24 miles per week. He walked 12 miles each way and travelled to and from school only once per week.
