A certain map shows two roads. Road A is 1 1/4 miles long but is 1 1/2 inches long on the map. What is the unit rate for inches per mile on this road? If Road B is 10 miles long, how long is Road B on the map?

300pi

step-by-step explanation:

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
