Answer 1

Dear

A distance of one international mile or 1 760 international yards or exactly 1609.344 meters travelled in one hour or exactly 3 600 seconds. 1 Mile per hour = 1.60934 kilometers per hour = 0.44704 meters per second (SI base unit). 1 mph = 0.447 04 m/s.

Also,

1 Centimeter per second is equal to 0.01 meters per second (SI unit).

So, car travels 2235.2 cm per second.
