Answer:
For the first question since 1 mile equals 1.6 km we have to divide, 14.4/1.6=9
For the second question the formula is to divide by 9, if we do this our anser will be 5.
For the third question the answer is 100,000 cm^2, the reason this is, is because if 1m^2=10,000cm^2 , 1x10=10 and 10x10,000=100,000
Hope I helped tell me if i have to clarify anything :)
