Question

what is the difference between ...
He would go to Delhi by car and he will go to Delhi by car ??​

Answer 1

Would is a past-tense form of will. If you are writing about past events, you can use it to indicate something that was in the future at that point in time, but is not necessarily in the future right now. In other words, you use would to preserve the future aspect when talking about the past.

Answer 2

Both are same

that वह कार से दिल्ली जाएगा
