Answer:

[tex]40h[/tex]

Explanation:

Use the velocity formula to solve

[tex]v = \frac{d}{t}[/tex]

In this question, you are given velocity [tex]v = 45km/h[/tex], and you are given a distance, [tex]d = 1800km[/tex].  Time in this question is what you'll need to find.

Start by rearranging the velocity formula, to isolate for t.

[tex]v = \frac{d}{t}[/tex]

Start by multiplying both sides by t

[tex]v(t) = \frac{d}{t}(t)\\\\vt = d[/tex]

Then divide both sides by v.

[tex]vt\frac{1}{v} = d/v\\ \\t = \frac{d}{v}[/tex]

Now that you've isolated for time, sub in your values and calculate.

[tex]t = \frac{d}{v} = \frac{1800km}{45km/h} = 40 h[/tex]
