How?
Madara(someone with comparable speed to him) with Rinnengan activated barely reacted to V1 Raikage

MS can't track Raikage's speed in V2

When Raikage at his top speed admitted to be Base Minato's inferior

Infact lately we've seen his Shunshin was so fast he crossed an insane distance to stop Kakashi before Sasuke(with EMS activated), Kakashi(with Sharingan), Naruto and co noticed a thing

So how he handles Minato's shunshin speed alone is questionable
Now add the fact he has greater fire power than him(even in SM), blocking and tearing apart Jinchuriki Obito chakra arms and almost destroying Jinchuriki Obito chakra ball defensive move at the same time with chakra arms and Senjutsu rasengan[

He also has much more chakra than him with Kyubi inside his body, so even outlasting is out of question. Infact we've seen how exhausted Hashirama was after few minutes of battle either in the VOTE or currently in this war
One marking that fvcks your life because they never disappear [

], and if he puts markings on whatever Hashirama tries to use as offense or shield, he could redirect destructive attacks like Bijuudama right there leaving Hashirama open and unaware of anything(and thus dying since he can't survive the explosion of a Bijuudama)
The fact he can use long range chakra arms more than 3times greater than a Bijuu in terms of length isn't helping either [

Hashirama can't even play the number advantage as well since Minato can also use clones Now add clones and has more chakra than him [

Not even as if clone would play a significant part in this battle that could change landscapes U_U
