Strokes 50 strokes a minute is recommended when using low tungsten blades, and 60 strokes a minute is recommended when using high speed steel blades.

450 power strokes per-minute 450/60=7.5 power stokes per second
Two stroke engines have one power/exhaust stroke and one intake/compression stroke per revolution per cylinder. A One cylinder engine at 900rpm produces 15 power strokes per second.
Your 4 strokes are Intake, Compression, Power, and Exhaust. On the first revolution is Intake on the down stroke, then compression on the up stroke, the next revolution is power on the down stroke and exhaust on the up stroke, so 2 revolutions complete a full cycle. That would mean 450 power strokes occur per minute, divide that by 60 to get 7.5 power strokes per second
A formula to find power stroke for an 8 cylinder 4stroke engine would be RPM/2=power strokes per minute. A 2 strokenengine has twice as many power strokes as a 4 so RPM=power strokes. Since rpm is not given in the question, I can't tell you how many power strokes there are.
55 on average
A four stroke engine has 4 strokes per cycle, whereas the two stroke engine has only 2 strokes per cycle. Since the 2 stroke engine has twice as many power strokes as a 4 stroke engine at a given rpm, the 2 stroke is capable of making nearly twice the power of a 4 stroke for a given displacement.
Strokes per hour refer to keystrokes. Usually typing is referred to as words per minute and strokes per hour are for a 10 key.
2 Strokes make much more power per cc than 4 strokes. For example a 2 stroke 125 and a 4 stroke 250 both make about the same power 4 strokes have much more low end torque though
