Write and solve an inequality that represents the given situation.

Question

If Lisa increased her rate by 15 mi/h, then in 2 hours she would travel a greater distance than she does in 3 hours at her present rate. What do you know about her present rate?

Answer 1

Just translate, if her present rate is x mph, then

2(x+15) > 3x

Answer 2

After I simplified I go:

2x+30>3x

30>x

So her present rate is less than 30 mi/h?
