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?

Answers (1)

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.
