Find the distance between Riverside and Milton if they are 15 cm apart on a map with a scale of 4 cm: 21 km. pls answer i will give points

66.9375

Step-by-step explanation:

from what you told me 4cm=21km

if you divide 21 by four, you get how many km is one cm. which is 5.25km

15 divided by 4 = 3.75

what we know is that 4 can go into 15 three whole times. so.. 21x3=63

now what we need to figure out is that .75

so, 75 is three quarters, so i divided 5.25 divided by 4 to get how much one quarter of a cm is in km. then i multipled that by three, giving me: 3.9375

63+3.9375= 66.9375

but you might have to round this i dont know if you do or not so thats the answer im giving
