Step-by-step explanation:
Use the velocity formula to solve
![v = (d)/(t)](https://img.qammunity.org/2023/formulas/physics/high-school/hx79k5znqx8lddiz67oc8jui1nt8kr6ifw.png)
In this question, you are given velocity
, and you are given a distance,
. Time in this question is what you'll need to find.
Start by rearranging the velocity formula, to isolate for t.
![v = (d)/(t)](https://img.qammunity.org/2023/formulas/physics/high-school/hx79k5znqx8lddiz67oc8jui1nt8kr6ifw.png)
Start by multiplying both sides by t
![v(t) = (d)/(t)(t)\\\\vt = d](https://img.qammunity.org/2023/formulas/physics/high-school/9kottpqgtd2au7b3weaigoztfrrdtosnpi.png)
Then divide both sides by v.
![vt(1)/(v) = d/v\\ \\t = (d)/(v)](https://img.qammunity.org/2023/formulas/physics/high-school/ys4g7cd1vyfbb329b7thern1z4sdk2zokm.png)
Now that you've isolated for time, sub in your values and calculate.
![t = (d)/(v) = (1800km)/(45km/h) = 40 h](https://img.qammunity.org/2023/formulas/physics/high-school/pstkjc7f66k1lmbwww9mu8tpvwac2ha1tv.png)
