The solution is x>18.
The problem tells us that 3 less than a number: x-3
is more than 15. >15
So the inequality is x-3>15. When we isolate x to simply the inequality, we add 3 to both sides, to get x>18.

Answer:
a=bc
Step-by-step explanation:
a/b=c
a=bc
7/4 miles in 11 minutes
x miles in 1 minute

7/4 x 1/11 = x
7/44 = x
So 7/44 miles per minute is the answer
