If a freight train travels 280 miles at 40  miles per hour, how many hours does it take the  train to travel 280 miles? |
--------------------------
Given: 40 MPH TO 280 MILES
Find:  MPH TO 280 MILES
Let M = MPH TO 280 MILES
 
  MPH TO 280 MILES      MPH TO 280 MILES 
 ------------------ =  ------------------
  280 MILES             280 MILES        
 
  M         40 
 -----  =  ----
  280       280
 
M =  280(40) / 280
 
M = 40 MPH
