3/4 of an hour is 45min so 45min x 3 equal 2h15 not 3h30 ! I hope I helped you

Automatically we know that he is wrong because even if we round it to make it a friendly number (lets say 1) it will still not equal 3 1/2
he has them for 3 1/2 days

even 1+1+1= 3 it still isnt enough and you arent even supposed to round

That is why he is wrong :) hope this helped
