Linear Inequalities

Question

Someone jogs 4 miles every day while jogging at a rate of 4 mph and walking at 2 mph. She only has 90 minutes so how much of each time is needed to fill 90 minutes perfectly. This is for linear inequalities. Also trying to figure out what the definitions for the variables are.

Answer 1

j represents the time jogging

90 - j represents the time walking

2(1.5 - j) + 4(j) = 4               90 minutes = 1.5 hours

 

Can yo solve for j and answer the question?
