The speed of the second plane is 3300/3 - 100 = 1000 km/h
It will take it 3.3 hours that is 3 hours + 3/10 hours = 3 hours + 3*6min
= 3 hours 18 minutes.

answer is 3hrs16 min...I don't know how they got it
sorry was worng
now I understood it is 3600 instead of 3300
3600/ 3 - 100 = 1000 km per hour
3600 km/h upon 1000 km/h =3.6 km/h
3 hours + 6/10 hours
convert 6/10 in minutes = 6/10×60 minutes
Therefore it will take 3 hours and 60 minutes
It means 4 hours

=3600/100*1(100km=1 hours
=36 hours
