Answer 2

$speed \: = \frac{distance}{time}$

We don't have any distance given in the question, so let us take the distance for example as 10 metres...

As we know the formula,

$speed \: = \frac{10m}{2s} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = \: \frac{5m}{1sec}$

Therefore, speed = 5 metre / sec
