Answer:

The speed of the bus is 74.242 kilometers per hour.

Explanation:

Let suppose that bus runs at constant speed and that speed is measured in kilometers per hour. Then, the speed of the bus (
v), in kiometers per hour, is determined by following kinematic expression:


v = (s)/(t) (1)

Where:


s - Travelled distance, in kilometers.


t - Time, in hours.

If we know that
s = 2.45\,km and
t = 0.033\,h, then the speed of the bus is:


v = (s)/(t)


v = 74.242\,(km)/(h)

The speed of the bus is 74.242 kilometers per hour.
