I NEED HELP :)) If you were travelling at 85 miles per hour, how long would it take to travel a distance of 670 miles?

It will take you about 2.8 hours.

drive 34 miles through a 55 MPH zone at 85 - .4 hours

get pulled over for speeding - .5 hours

drive 33.15 miles through a 55 MPH zone at 85 - 0.39 hours

enter a school zone 25 MPH speed limit

get pulled over for speeding, cop considers arresting you, you finally convince him you are rushing to see your mother on her death bed just 1/2 mile down the road. After 1.5 hours you have the officer convinced enough to let you proceed, but he will follow you - 1.5 hours.

drive .85 miles to arrive at your own house - .01 hours

officer realizes your mother is not there and arrests you

Total time - 2.8 hours.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
