you can easily solve this by using a simple rule of three

Step one

Define

`1\ quarter\ mile =(1\ mile)/(4) \\`

Step two

`1\ quarter\ mile =(1\ mile)/(4) \\x\ quarter\ mile=4\  miles\\\\do\ the\ relation\\\\(1\ quarter\ mile )/((1\ mile)/(4) )= (x\ quarter\ mile )/(4\ miles )\\\\solve for\ x\\\\(4\ miles*1\ quarter\ mile )/((1\ mile)/(4) )=x quarter mile\\x\ quarter\ mile=16\ quarter\ miles`
