Fernando vai à pé pra escola. Todos os dias ele sai as 6:30 e chega na escola as 6:55. Nisso ele percorre 2km. Na volta pra casa
alexgriva [62]
<span>Como sabemos a quantidade de tempo que leva a Fernando para chegar à escola, quando sua classe começa e termina, e quanto tempo leva para chegar em casa, podemos resolver quanto tempo Fernando estava longe de casa. O que fiz primeiro foi adicionar os 40 minutos que levou Fernando para chegar em casa às 11:30 e chegou às 12:10. Foi quando Fernando chegou em casa, então tudo o que precisamos fazer agora é fator em 6:30 e descubra quanto tempo ele estava fora da casa. Eu fiz isso contando as horas e subtraindo os minutos extras. O tempo que Fernando acabou é de 5 horas e 40 minutos.</span>
