Respostas
Um pentágono possui 5 lados
Como ele corre 13 voltas e um total de 12,35 km por dia, primeiro devemos descobrir quantos km temos em 1 volta:
_____
12,35 ÷ 13 = 0,95 km
Logo ele corre 0,95 km por volta
Já que um pentágono possui 5 voltas, devemos dividir a distância de cada volta por 5:
_____
0,95 ÷ 5 = 0,19
Logo ele percorre 0,19 km por cada lado
Já que devemos encontrar a resposta em metros, devemos converter 0,19 km em metros:
_____
0,19 × 1000 = 190 metros
