Question

CONVERT INTO KILOMETERS(IN DECIMALS):
(a) 4 m
(b) 4 km 3 m
(c) 18 km 159 m

Answer 1

(a) 4 m = 0.004 km
(b) 4 km 3 m = 4.003 km
(c) 18 km 159 m = 18.159 km ..

Answer 2

(a) 4m =  4/1000 km 
            = 0.004 km

(b) 4 km 3 m = 4 km + 3 m
                [3 m = 3/1000 km = 0.003 km]
                       = 4km + 0.003 km
                       =  4.003 km.

(c) 18 km 159 m = 18 km + 159 m
                 [159 m = 159/1000 km = 0.159 km]
                             = 18 km + 0.159 km
                             = 18.159 km.
