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?


It is given in the question that,

Distance travelled by bus = 15 km 268 m


= (15 + ) km


= 15 + 0.268 km


= 15.268 km


Distance walked in the evening = 7 km 7 m


= (7 + ) km


= 7 + 0.007 km


= 7.007 km


Also,


Distance travelled by foot = 500 m


= km


= 0.500 km


Therefore,


Total Distance = 15.268 + 7.007 + 0.500



Hence, total distance of school from her residence = 22.775 km
