Answer:
Lets solve = 3/5 ÷ 1/2
3/5 ÷ 1/2
 = 3/5 × 2/1
 = 3 × 2/5 × 1
 = 6/5
In mixed fraction its 

____________________
Now lets solve "a" option
3/5 × 2 
= 3 × 2/5 × 1
 = 6/5
In mixed fraction

So option a = 3/5 x 2/1 is ur answer

Answer:
Yes I believe that is correct. 
Step-by-step explanation:
Im not sure why the m is first because it would be 180 miles first but I think you are correct, I think you should wait for another answer tho because I am not 100 percent sure. :)
 
        
             
        
        
        
Answer: 
Step-by-step explanation:
 1. To find the equation asked, you must add the times:
 
 Where  is the time takes Lilly in her path to work and
 is the time takes Lilly in her path to work and  is the time takes Lilly in her path to home.
  is the time takes Lilly in her path to home.
 2. You must use the following formula of speed and solve for the time
 
 Where n is the distance, V is the speed and t is the time.
 3. You know that Lilly takes a train each day to work that averages 35 miles per hour, then, you can write the following expression:
 
 4. And her train ride follows the same path at 45 miles per hour:
  
 5. Then, you obtain the following equation:
