To find out how many kilometers a line of length 7½ cm would represent, we can use the proportion of the given information:
5 cm = 40 km
7½ cm = x km
Setting up the proportion:
5/40 = 7½/x
Cross-multiplying:
5x = 40 * 7½
5x = 300
x = 60
Therefore, a line of length 7½ cm would represent 60 km, so the answer is D. 60km.
