Problema Solution
A car enters an interstate highway 15 miles north of a city. The car travels due north at an average speed of 62.5 miles per hour. Write an equation to model the car's distance from the city after traveling for hours
Answer provided by our tutors
Since the car enters 15 miles North of the city and is traveling further north, the start point is positive 15 so the equation is:
d = 62.5h + 15,
where h represents the number of hours and d is the distance traveled.
