Answer:

$\boxed {\tt s=133 (1)/(3) \ or \ 133.333333 \ km/hr}$

Step-by-step explanation:

We want to find speed, so we can use the following formula.

s=(d)/(t)

where
is the distance traveled and
is the time.

We traveled 400 kilometers in 3 hours. Therefore,

$d= 400 \ km \\t= 3 \ hrs$

Substitute the values into the formula.

$s=(400 \ km )/(3 \ hrs)$

Divide

$s= 133.33333 \ km/hr$

$s= 133 (1)/(3) \ km/hr$

The speed is 133 1/3 or 133.33333 kilometers per hour.
