# A racing tortoise covers 360 cm in 9 seconds. How fast is it walking?

Oct 20, 2016

The speed is 40 cm/sec or 0.4 m/sec

#### Explanation:

This is a distance speed time question.

$360$ cm is a distance, and $9$ seconds is the time taken

"How fast ?" is asking for the speed.

$\text{speed" = "distance"/"time}$

$\text{speed" = 360/9 = 40 " cm per sec}$

A more usual unit for speed would be m/sec, which would be
$0.4$ m/sec
