How much time does it take for a bird flying at a speed of 45 kilometers per hour to travel a distance of 1800 kilometers?

To solve this problem, let us first assume that the bird was

flying at zero acceralation (constant velocity) so that we can use the

equations for linear motion. The formula relating velocity, distance and time

is:

v = d / t

where

v = velocity = 45 km / hr

d = distance travelled = 1800 km

t = time elapsed = (unknown)

Rewriting in terms of t:

t = d / v

Substituting the given values to find for t:

t = 1800 km / (45 km / hr)

t = 40 hr

Therefore it takes about 40 hours for the bird to travel

that distance.
