Question

An ostrich was 960meters east of its nest. It ran west at a constant velocity for 160seconds. In that time, it ran halfway to its nest. What was its velocity?

Answer 1

Answer is 3 m/s.

Step-by-step explanation:-

The ostrich ran at a constant velocity, so it's velocity was :

$velocity = \frac{distance}{time}$

It is said that the bird ran for 160 seconds and it made it half-way to its nest, so the distance was :

$distance = \frac{960 \: metres}{time}$

$distance = 480 \: metres$

And the velocity is :-

$velocity = \frac{480 \: metres}{160 \: seconds}$

$velocity = 3 \: m/s$

Therefore, the ostrich ran at a velocity of 3 m/s .
