Answer:
125 kilometres does 1 1/2 decimetres represent
Step-by-step explanation:
Given
3 cm = 25 KM (Representative)
we have to find value of 1 1/2 decimetre
1 1/2 decimetre = (1*2+1)/2 decimetre = 3/2 decimetre
we know
1 decimetres = 10 cm
3/2 decimetres = 3/2 *10 cm = 15 cm
thus, we have to find 15 cm on the 3 cm = 25 KM map.
3 cm = 25 KM
1 cm = 25/3 KM
15 cm = 15*25/3 KM = 125 KM
Thus,
125 kilometres does 1 1/2 decimetres represent
