Explanation / Answer

3)-

a) -

map reading = 6 cm

actual distance = 10 km = 10 x 1000m = 10000m = 10000 x 100 = 1000000 cm

scale = 6:100000 = 1:166667

b) -

map reading = 9 in

actual distance = 3.5 miles = 3.5 x 1.6 km = 5.6km = 5.6 x 100000cm = 560000 cm

scale = 9:560000 = 1:62222

4)-

a) - scale = 1:200000

1cm represents = 200000 cm = 200000/100000km = 2km

b)- scale = 1:190080

1 inch represents = 190080 inch = 190080 x 2.5cm = 475200cm = 475200/100000km = 4.752km = 4.752/1.6miles= 2.97miles
