Scale

1.     Two points are 5.7 apart on a 1:24000 map. What is the ground distance in miles and KM?

2.     Two points are 5.7 apart on a 1:24,000 map.  On another map, they are 4.4 apart.  What is the scale of this map?

3.     A field measure 5.7 by 4.4 on a 1:24,000 map.  What is the area in square miles and square KM?

4.     A lake measures 560 full cells and 1048 partial cells with 1/8 grid paper. Given that the map has a scale of 1:50,000, what is the area of the lake?
