First, let's isolate t! Make sure to change your signs when you change from one side of the equation to the other.
3/2 + t = 1/2
t = 1/2 - 3/2
Now, we can solve for t!
t = 1/2 - 3/2
t = -2/2
t = -1

Answer:
Step-by-step explanation:
Both cars, X and Y travelled 80 miles each.
Speed = distance/time
If car X took 2 hours to travel 80 miles, it means that the speed at which car X travelled is
80/2 = 40 mph
If car Y traveled at an average speed that was 50 percent faster than the average speed of car X, it means that the speed at which car X travelled is
40 + 0.5 × 40 = 60 mph
Time = distance/speed
Therefore, time taken by car Y to travel 80 miles is
80/60 = 1.33 hours
