Map scale distance

The particular map has a scale of 1:75000
a) The distance between the two places on the map is 42 mm. What is the actual distance?
b) How long would the distance show, 15.75 km on the map?

Final Answer:

a =  3.15 km
b =  21 cm

Step-by-step explanation:

k=75000 A=4.2 cm km=4.2:100000  km=4.0105 km a=A k=4.2105 75000=2063 km=3.15 km
B=15.75 km cm=15.75 1000 100  cm=1575000 cm  b=B/k=1575000/75000=21 cm
