Solution

The correct option is D
Can’t be said

When we use the formula,

$S p e e d = \frac{D i s t a n c e}{T i m e}$

We get the average speed for that time interval, but we cannot say what the actual speed at a particular instant or in between that particular interval of time because it is not given that motion is uniform. Hence, actual speed at 8:45 AM can't be said.
