A car enters a interstate highway 15 mi north of the city. The car travels due north at an avrage speed of 62.5 mph. Write an equation to model the car's distance from the city after traveling for h hours.
d = 15 + 62.5 t
To write an equation to model the car's distance from the city after traveling for h hours, we first need to determine the car's initial distance from the city.
We are given that the car enters the interstate highway 15 miles north of the city. So, the initial distance from the city is 15 miles.
The car travels due north at an average speed of 62.5 mph. Since the car is traveling directly north, the distance traveled is equal to the speed times the time.
Therefore, the distance the car travels after h hours can be represented by the equation:
Distance = Initial distance + (Speed * Time)
Distance = 15 + (62.5 * h)
So, the equation to model the car's distance from the city after traveling for h hours is:
Distance = 15 + 62.5h
