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?

Answer 1

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
