Question RPM vs speed vs torque

Hi friends
I'm new to the community........

1. I wanna ask how can a wheel at higher speed can be at lower rpm........i mean when we accelerate high on a lower gear the rpm is very high but after shifting up at same speed rpm is less.........how is it possible...........
rpm means how many rotations we take per minute ..........so if we are at a higher speed that means wheel is rotating fast so we are definitely at higher rpm (which is seen within same gear) but then why after shifting however we are at high or same speed, we are at lower rpm
And secondly.....
2. How peak torque can be achieved at lower rpm.............
when rpm is higher i.e we get more no of rotations which is only possible if engine gives the wheel more coupling force i.e torque so greater the rpm greater should be torque............but this is not so i guess.....................
thanx in advance for a good answer............
and plz tell me in general language not ny equations and all...
