Question

If a train travels 500 kilometers from Stockholm to

Copenhagen and the journey takes 5 hours, then what is the
train's average speed in kilometers per hour?

Answer 1

Hello,

Average speed is total distance divided by total time. From the problem, our total distance is given as 500 kilometers and given time is 5 hours. Therefore, the average speed is:

`\displaystyle{v_\text{average}=\sum_(i=1)^n (s_i)/(t_i)}\\\\\displaystyle{v=\frac{500\ \text{km}}{5 \ \text{h}}}\\\\\displaystyle{v=100 \ \text{km/h}}`

Therefore, the average speed is 100 km/h. Please let me know if you have any questions!
