On a map with a scale of 1:500,000, the aerial distance is equal to 12 cm. The distance by rail is equal to 100 km. The road distance is 92 km. Express the air, rail, and road distance in a step-by-step ratio.

Correct answer:

p = 15:25:23

Step-by-step explanation:

v1=12 cm km=12:100000  km=0.00012 km s1=v1 500000=0.0001 500000=60 km s2=100 km s3=92 km  p = s1:s2:s3 p =  60:100:92 60=2235 100=2252 92=2223 GCD(60,100,92)=22=4  k=GCD(60,100,92)=4  p=15:25:23
