Car a travels 180 in 3 hours. car b travels 100 miles in 2 hours. how far apart will the cars be in 4 hours

you would divide 180 and 3, that's how much car a travels in an hour. Do the same for car b so 100÷2

you would get 60 for 'a' and 50 for 'b'

but you still need to find how much in four hours so you would times those numbers by 4

car a- 240 in 4 hours

car b- 200 in 4 hours

so they would be 40 apart

hope that made sense :)

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

the answer is 5/14.

hope this .
