A lot.
It's Typically faster than by Boat or Car however it is usally cheaper than a plane.
Generally speaking aeroplanes are much faster than boats. The main factor being the medium through which they travel. There are certain specially built vessels that can travel faster than some aeroplanes but for sheer speed air travel will always be faster.
No plane is faster than light.
A fast train can be faster than a slow plane. But even a regular plane will be faster than fast train.
a rocket travles faster than a jet plane
It all really depends on what models of jet and plane you're refering to...
No. A helicopter is not faster than an airplane. A helicopter could fly at about 400-650 kph. But a plane could fly much faster than that.
If the frame of reference is the ground, and if you are running forward, you are indeed moving faster than the plane. If you are running toward the rear of the plane, you are moving slower than the plane.
by boat
Not unless the plane is an ultralight, which can cruise between 40 and 55 mph (legal speed will not exceed 80 mph when calibrated to 55 mph). A cheetah's top sprint speed is about 65 mph (104 kph).
if you mean eights or pairs, than eights are faster BY FAR. Although the boat is bigger and heavier, having 4x times the man power and 4x the oars propels the boat throughout the water much faster than a boat with only 2 people and 2 oars.
Most rockets are much faster than fighter aircraft.
