The one that matches is A
Part 1)
we have
the scale is 
the distance on a map is 
we know that
The scale is equal to the distance on a map divided by the real distance
Let
x------> distance on a map
y-------> real distance
S-------> scale

In this part we have

Find the value of y

Substitute the values


Convert to kilometers

Part 2)
In this part we have

Find the value of x

Substitute the values


Convert to centimeters

therefore
the answer is
The distance is 
75.6%
78 - 19 = 59
59 / 78 = .75641
.75641 x 100 = 75.641
