We are given an enumeration of A by a 1-1 correspondence
f : N → A. This enumeration has no repetitions.
Hint. Prove that you can use the enumeration f to obtain a different enumeration where each member of A is enumerated infinitely many times.
You will find the traversal with north-east arrows, profitable. Traversal of what? (This I leave to you :)

77

step-by-step explanation:

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

45.36 feet per second.

step-by-step explanation:

to find the most accurate determination for the number of feet per second tyrone traveled on his way to work let us convert miles to feet and minutes to seconds.

1 mile = 5280 feet.

1 minute = 60 seconds.

now we will divide 158400 by 3492 to find the most accurate determination for the number of feet per second tyrone traveled on his way to work.

therefore, tyrone traveled on his way to work at the rate of 45.36 feet per second.
