Question
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?
Solution
Distance travelled by bus = 15 km 268 m
= `[(15 + 268/1000)]` km
= 15.268 km
Distance travelled by car = 7 km 7 m
=`[(7 + 7/1000)]` km
= 7.007 km
Distance walked by Sunita = 500 m
= `500/1000`
= 0.500 km
The total distance of the school from her residence is
15.268
7.007
+ 0.500
22.775
∴ The total distance of the school from her residence is 22.775 km
