# Q: 6    Sunita travelled 15 km 268 m by bus, 7 km 7 m by car and 500 m on foot in order to reach her school. How far is her school from her residence?

P Pankaj Sanodiya

The distance travelled by bus = 15 km 268 m

The distance travelled by car = 7 km 7 m

The distance travelled by foot = 500 m

As we know.

For adding two numbers their unit must be the same.

So,

$15 km +268 m = 15 km + \frac{268}{1000}km$

$= 15 km + 0.268km$

$= 15.268km$

Also

$7km+7m=7km+\frac{7}{1000}km$

$=7km+0.007km$

$=7.007km$

And,

$500m=\frac{500}{1000}km$

$=0.5km$

So,

The total distance Sunita traveled = 15.268 km + 7.007 km + 0.5 km

= 22.775 km

Hence the distance between Sunita's residence and school is 22.775 km.
