Answer:
The speeds of each car are 45 mph and 30 mph.
Step-by-step explanation:
Since two cars leave from the same place and travel in the same direction, and one car travels one third times as fast as the other, and after 3 hours, they are 45 miles apart, to determine what is the speed of each car you must perform the following calculation:
45/3 x 2 = X
15 x 2 = X
30 = X
Therefore, the speeds of each car are 45 mph and 30 mph.
