Calculating the Speed given the Distance and Time
Answer:
[tex]4.\overline{4} \frac{\mathrm{km}}{\mathrm{min}}\\[/tex]
Explanation:
The speed, [tex]r[/tex], is calculated by [tex]r = \frac{d}{t}\\[/tex] where [tex]d[/tex] is the distance traveled and [tex]t[/tex] is the time. We are given the distance traveled of the bus, [tex]200 \mathrm{km}[/tex], and the time it has traveled, [tex]45 \mathrm{min}[/tex]. So, the speed of the bus, [tex]r[/tex], is calculated as...
[tex]r =\frac{200 \mathrm{km}}{50 \mathrm{min}} \\ r = \frac{40 \mathrm{km}}{9 \mathrm{min}}[/tex]
The speed of the bus is [tex]\frac{40 \mathrm{km}}{9 \mathrm{min}}\\[/tex] or [tex]4.\overline{4} \frac{\mathrm{km}}{\mathrm{min}}\\[/tex].
