Sunita travelled 15 km 268 m by bus, 7 km 7 m by car and 500 m by foot in order to reach her school. How far is her school from her residence?

Answer:

Distance travelled by bus = 15 km 268 m

\[=15\,\,\text{km}+\left( \frac{268}{1000} \right)\text{km}\]

\[=15.268\,\,\text{km}\]

Distance travelled by car

\[=7\text{km}\,\,7\text{m}\]

\[=7\,\text{km+}\frac{7}{1000}\text{km=7}\text{.007}\,\,\text{km}\,\]

Distance travelled by foot

\[=500\text{ m}=\frac{500}{1000}\text{ km}\]

\[=0.500\text{ km}\]

Total distance = 15.268 km + 7.007 km + 0.500 km

= 22.775 km
