An airplane flies 3/4 of a mile in 1/8 of a minute what is the airplane speed in miles per minute

Step-by-step explanation:

Use proportions to figure this out.  On the top you'll have miles and on the bottom you'll have minutes.  I am going to change 3/4 to .75 and 1/8 to .125:

We want to know how many miles per 1 minute that is.  So we have the unknown on top in a new ratio, with 1 on the bottom:

This second ratio is allowing us to calculate what the decimal ratio is in miles per 1 minute.  Cross multiply to get

.125x = .75 so

x = 6 miles

That tells us that the decimal ratio is equivalent to 6 miles per minute

Lisa is correct as 3 multiplied by 7 is 21 for the comparison model you should draw three boxes on top of three boxes in three of those boxes put a tree and in one of those boxes put a car that should work.
