Final answer:
The correct equation to find out how far one can drive in 'h' hours at 60 mph is 'd = 60h'. It showcases a linear relationship between distance and time wherein multiplying 60 mph by the number of hours gives the distance traveled.
Step-by-step explanation:
The correct function to determine the distance one can drive in 'h' hours at a constant speed of 60 miles per hour is d = 60h. This equation represents a linear relationship between time (h) and distance (d), where 'd' stands for the distance in miles and 'h' represents the time in hours. To use this function, simply multiply the speed (60 mph) by the number of hours driven.
