Question

Sunita traveled $15km268m$ by bus, $7km7m$ by car and $500m$ on foot in order to reach her school. How far is her school from her residence?

Answer 1

Use the concept of addition od decimals:

Distance travelled by bus $=15km268m$

$=15\times 1000m+268m$

$=\left(15000+268\right)m=15268m$

Distance travelled by car$=7km7m$

$=7\times 1000m+7m$

$=\left(7000+7\right)m=7007m$

Distance travelled on foot $=500m$

Total distance travelled $=15268m+7007m+500m$

$=22775m$

$=\frac{22775}{1000}km=22.775km$

Hence, her school is $22.775km$ away from her residence.
