Verbs of motion
In Russian we use the accusative case with the prepositions в and на
when the noun indicates the direction (place) toward which something or someone
is moving. The place will be in the accusative case, and it will answer
the question куда?
Они идут в ресторан.
Сергей едет на работу.
Time
- In Russian we use the expression "сколько времени?" to ask "for how long"
something takes place. Another meaning of this question is "What time is it?".
- The answer to this question is always in the accusative case:
Сколько времени вы читали?
Весь день.
Всю субботу.
Всё утро.
