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 :)

c

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
