<h3>1. Todos los pasajeros llegaban al mismo tiempo
</h3>
To write each sentence in the imperfect, we need to change the conjugation of the verbs of each sentence. Recall that the imperfect is used to talk about past actions, conditions, or events that occurred regularly or frequently or that were in progress in a moment in the past. At first, the sentence is in the simple present, so llegan is the conjugation of the verb llegar for the third person plural in the simple present. On the other hand, llegaban is the conjugation of the verb llegar for the same person in the imperfect.
<h3>2. Hacía frío y nevaba
</h3>
Here we have two verbs hacer and nevar. So the conjugations of these verbs for the third person singular in the simple present are hace and nieva, respectively. For the same person, the conjugations of these verbs in the imperfect are hacía and nevaba. So snowing is an event that occurred regularly or frequently or that were in progress in a moment in the past.
<h3>3. Nosotros conocíamos a mucha gente que venía de Japón
</h3>
Here we have two verbs conocer and venir. The verb conocer stands for the first person plural (nosotros) here and the verb venir stands for the third person singular here. Hence the conjugations in the simple present for the corresponding person are conocemos and viene. Accordingly, by changing these conjugations to match the imperfect, we have that the new conjugations are conocíamos and venía
<h3>4. ¿Había un lugar donde la gente hablaba latín?
</h3>
Here we have two verbs haber and hablaba. There are two ways to ask questions using the verb haber in the imperfect. Using the word había (is there - singular) and habían (are there - plural). Since we are asking for <em>one place</em> (singular), we choose había. The other verb hablar changes from habla (simple present) to hablaba (imperfect) for the third person singular.
<h3>5. Ibas a visitar a tus abuelos</h3>
Here we use the verb ir <em>(to go). </em>First of all, we use the word vas that is the conjugation of the verb ir for the second person singular in the simple present. To write this sentence in the imperfect, we need to change the conjugation vas. Therefore, this new word is ibas that also matches the second person singular.
