The distance between vancouver and winnipeg is approximately 1850 km in a straight line. the distance on a map is 3.7 cm. write a scale statement for the map. what scale factor was used to make the map.

3.7cm on the map represents 1850km in reality

3.7cm : 1850km

1cm : 1850/3.7 km

1cm : 500km

Scale statement for map is :          1cm : 500km.

That is 1cm on map represents 500km.

1cm : 500km.       Recall 1km = 1000m = 100 000cm

1cm : 500* 100000cm

1cm : 50 000 000cm

1: 50 000 000.

Scale factor is 50 000 000.   

Ican't do any of the other stuff, but i can get you started. the answer, i believe, is $2.50.
