On a certain map, 3 centimetres represents 25 kilometres. How many kilometres does 1 1/2 decimeters represent?

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
