Question

Car X travels 144 miles in 3 hours.
a. Write the equation of the line that describes the relationship between distance and time. Use x for the time in hours and y for the distance in miles.

Answer 1

Distance = rate × time. The speed is 144 miles / 3 hours = 48 mi/h, so the line is
y = 48x
(where x is hours and y is miles).
