Yes.
Hertz is a unit of measuring frequency. It is 'cycles per second' or just second^-1 or 1/seconds. It is not the same as seconds (a measure of time or elapsed time).
the same
Yes. 1 Hertz (Hz.) = 1 cycle per second Units are 1/seconds = sec^-1
No. Square feet are square.

same question
No
The same as 4.7 seconds.
The first half is 5.5 inches. The second half is the same.

Yes.
20 feet in 0,5 seconds ==> 40 feet per second 40 feet per second * 3 seconds = 120 feet
300 x 10 x 2 = 6000 The plane will travel 6000 feet.
55 meters in 6.47 seconds would be the same as 60 yards in 6.454 seconds.
Yes, usually. Most minutes have 60 seconds; although now and then a leap second is added.
