Riders on tandems and bicyclesLesson 220 of the lessons course of Mova's primary school: 3 sentences, each with its syntax tree and pragmatics. The lessons are written for Mova, and their agreed trees are part of Mova corpus 0.4 (CC BY-SA 4.0).0A tandem is a bicycle made for two: it has 2 seats, one behind the other, and 2 wheels like an ordinary bicycle.1If some riders are on full tandems and the rest ride a bicycle each, first find how many ride alone.213 riders, 4 full tandems: 4 × 2 = 8 ride tandems, 13 − 8 = 5 ride bicycles, so 4 + 5 = 9 cycles and 9 × 2 = 18 wheels.← previousWheels on cyclesnext →Days and weeks↑ back to LessonsThis page in Markdown → https://md.mova.elamur.ai/free/en/corpora/school/lessons/220-riders-on-tandems-and-bicycles/
