Solution

Addition of decimals:
Distance travelled by train $= 12 k m 50 m = 12 + \frac{50}{1000} = 12 + 0.050 = 12.050 k m$ $(S i n c e 1 k m = 1000 m, 1 m = \frac{1}{1000} k m)$
Distance travelled by auto-rickshaw $= 3 k m 550 m = 3 + \frac{550}{1000} = 3 + 0.550 = 3.550 k m$
Distance travelled by walking $= 750 m = \frac{750}{1000} k m = 0.750 k m$
Total distance travel $= 12.050 + 3.550 + 0.750$
$12.050 3.550 + 0.75016.350$
Therefore, total distance travel $= 16.350 k m o r 16 k m 350 m$
