To convert miles to feet you multiply by 5280
To convert hours to seconds you divide by 3600
so you multiply 64 by 5280/3600 which comes to 93.87 ft/s Answer
Suppose that the number u were thinking about is x thus :

Multiply both sides by 4



Divide both sides by 3


The sum of the adjacent angles of a parallelogram is always equal to 180°.
So we know that

.
When we simplify that expression:

Isolate the y by divide both sides by 3:
