Question

The 250m between Sam's house and the tennis court corresponds to 5 cm on a town map. What is the actual distance between Sam's school and the library if they are 8.4 cm apart on the same map? Plz answer in meters, thanks!

Answer 1

Answer:

420 m

Step-by-step explanation:

250m >>> 5cm

Everything must be of the same unit so 250 x 100 =25000 cm

If The distance between the school and the library is 8.4 then,

25000 >>> 5

?? >>> 8.4

We do cross multiplication

(25000 x 8.4) ÷ 5 = 42000cm

42000 ÷ 100 = 420 m

Answer 2

420 m

250m to 5cm

m and cm are not the same unit so we have to convert m to cm: 250 x 100 =25000 cm

If the distance between is 8.4

25000 is to 5

?? >>> 8.4

We do cross multiplication

(25000 x 8.4) ÷ 5 = 42000cm
