Answer:

Ans.    64 cm

Step-by-step explanation:

we have to use the ratio of actual distance and distance on projection here.

Given,

Ratio of distance in projection and actual distance is  1:200,000

That means, 1 cm in projection will be 200,000 cm in actual distance.

Here,

Actual distance is 128 km.

we know, 1 km=100,000 cm

Now,  128 km=128,00,000 cm

So, actual distance is 128 00 000 cm.

Since, 200000 cm in actual distance means 1 cm in projection.

So,

for 12800000 cm in actual distance means 12800000/200000 cm in projection.

So, in the screen distance will be-

12800000 / 200000

=64 cm
