Question

The distance between NY and Boston is 306 km. How long is it on a map (in cm) drawn at a scale of 1:1,200,000?

Answer 1

Answer:

Given:

1 cm  = 1200000 cm

using conversion : 1 km = 100000 cm

$1 cm = 12 \times 100000 cm$

1 cm = 12 km

or we can write this as:

12 km  = 1 cm  

306 km = $\frac{1 \times 306}{12} = \frac{306}{12} = 25.5$ cm (by unitary method)

Therefore, the distance between Ny and Boston on map(in cm) is, 25.5 cm

Answer 2

Answer:

25.5 cm

Step-by-step explanation:

Scale of 1:1,200,000 means 1 cm equals to 12 km.

Now divide 306 by 12 to you will get 25.5 cm.

So the answer is 25.5 cm in 306 distance.
