what is the time it takes to walk more than 1,000 feet? need a equation or a inequality to represent the problem

Question

Billy is walking home from school at a rate of 250ft per minute. His school is 5,000 feet from his home. The equation y=250x represents the distance Billy walks, where x represents the time in minutes in feet and y represents the distance in feet..

Answer 1

Not exactly sure what the question is, but if you want an inequality that represents how long it takes to walk more than 1000 feet you would write

 

250x > 1000

 

and solve it to get x > 4 minutes

 

If you want to know how long it takes Billy to walk home, you would write

 

250x = 5000

 

and solve it to get x = 20 minutes
