Melanie walked 2.2 miles. Cathy walked 1.75 times as far. This means that you need to do 2.2 * 1.75 which equals 3.85. To find how much further, do 3.85 - 2.2 which equals 1.65. Therefore Cathy walked 1.65 more miles than Melanie.
A is the answer because it is the widest variety
To solve this, we are going to set up a simple rule of three: If 20% are 48 cars, 100% how many cars will be:

Now, we can express this as a proportion ans solve for

:


We can conclude that there are 240 cars in the parking lot.
The correct answer is 400.
3/x+1=5/11 first cross multiply
3*11=33 and 5*x+1= 5x+5 5x+5=33
then subtract 5 on both sides 5x+5-5=33-5
5x=28 so divide 5 on both sides
5x/5=28/5
x= 5.6
