in a map of scale of 1 cm represents 75 km. what should be the distance on a map if two towns are 400 km away?​

≈ 5.3 cm.

Step-by-step explanation:

If 1 cm. represents 75 km. then dividing that by 400 to get 5.3333.. or just 5.3, we can safely say that on a map, two towns that would be 400 km. apart, would only appear a bit over 5 cm. apart on a map!

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
