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.
.
Distance covered in 3 hours = 144 miles
Distance covered in one hour = 144/3
= 48 miles
Let car covers y miles in x hours.
Time = distance/speed
Here speed is constant so,
distance is directly proportional to time.
So equation of line describing relation between distance and time is y = 48x
B. A distance and Tiem graph is a graph that represents the relationship because you can see how far it goes within a certain time and you can find out the speed of the vehicle D
