Question

Write an inequality to model the situation. the maximum speed on the highway , x is 55 mi/h

Answer 1

A maxm speed of 55 mph means that the speed has to be lexx than or equal to 55

x <= 55

Answer 2

We have been given the maximum speed on the highway which is 55 mi/hr

So, it has to be less than or equal to 55 because maximum it can go up to 55.

The required inequality will be
`x\leq55`

We can take an example of a moving car on a highway which is moving with the speed of 45 mi/hr

And also the stationary car on highway because its speed will be zero which is satisfying the inequality condition.
