tell with solution not only the answer..​

Answer 1

Answer:

2100 km

Step-by-step explanation:

Scale of the map = 1:30000000

This means that

1 cm on map is actually

3,00,00,000 cm distance

Let's first convert cm into km

3,00,00,000 cm = 3,00,00,000 * 1/100 [ As,1m=100cm]

                           = 3,00,000 m

                           = 3,00,000*1/1000km [As,1km=1000m]

                           =300 km

So, 1 cm on map is 300 km actual distance

We need to find actual distance if distance in map is   7 cm.

Let actual distance be y km

Thus, our table looks like

                Distance in map(in cm)   1       7

                Actual distance(in km)  300   y

Now, As actual distance increases,

distance in map also increases.

Therefore, they are in direct proportion.

1/300 = 7/y

or, y*1 = 7*300

or, y = 2100

or, y = 2100 km.

Therefore, The two cities are actually 2100 km apart.

Answer 2

Answer:

Scale of the map = 1:30000000

This means that

1 cm on map is actually

3,00,00,000 cm distance

Let's first convert cm into km

3,00,00,000 cm = 3,00,00,000 * 1/100 [ As,1m=100cm]

                           = 3,00,000 m

                           = 3,00,000*1/1000km [As,1km=1000m]

                           =300 km

So, 1 cm on map is 300 km actual distance

We need to find actual distance if distance in map is   7 cm.

Let actual distance be y km

Thus, our table looks like

                Distance in map(in cm)   1       7

                Actual distance(in km)  300   y

Now, As actual distance increases,

distance in map also increases.

Therefore, they are in direct proportion.

1/300 = 7/y

or, y*1 = 7*300

or, y = 2100

or, y = 2100 km.

Therefore, The two cities are actually 2100 km apart.
