How much time does it take for a bird flying at a speed of 45 kilometers per hour to travel a distance of 1,800 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.

Step-by-step explanation:

An obtuse angle is one that is greater than 90° and less than 180°. A scalene triangle is one whose 3 sides are unequal in length.

SSS (side-side-side) congruence occurs when the lengths of the sides (every triangle has 3 sides) of a triangle match the lengths of the sides of another triangle.

SSS congruence is one of the theorems that apply to triangles.

Rigid motion is: any way of changing the position of the points on a plane, such that the relative distance between points remains the same, as well as their relative positions. Types of rigid motion include: glide reflection, translation, and rotation.
