Step-by-step explanation:
I guess it will only blink, if the speed is over the speed limit.
because "within 5 mph of the site limit" means actually the interval of 5 mph below to 5 mph above the speed limit.
and what happens, if the car is even faster than that ? no more blinking - normal again ?
many greetings from me to your teacher - the problem descriptions need to be more precise.
so, the inequality must likely fitting to the problem description would be
speed limit < car speed <= speed limit + 5
please note the < sign in the left, as I assume that when the car is going precisely as fast as allowed, it is no reason to warn the driver. only when the speed limit is exceeded.
I am not sure what is meant by the scale value inequality, as we have no further information about specific values or limits.
but I can give an example.
let's assume a 45 mph speed limit zone.
then the inequality to drive the blinking mode of the sign would look like
45 < car speed <= 50
