Final answer:
The speed of the first train is 90 mph and the second train is 40 mph. Therefore, it is true that the first train is traveling faster than the second train.
Step-by-step explanation:
To determine which train is traveling faster, we calculate the speed for each train by dividing the distance traveled by the time taken to travel that distance.
For the first train that travels 30 miles in 1/3 hour, we calculate the speed as follows:
- Speed = Distance / Time
- Speed = 30 miles / (1/3) hour
- Speed = 30 miles * 3 = 90 miles per hour (mph)
For the second train that travels 20 miles in 1/2 hour, we calculate the speed as follows:
- Speed = Distance / Time
- Speed = 20 miles / (1/2) hour
- Speed = 20 miles * 2 = 40 miles per hour (mph)
Since 90 mph is greater than 40 mph, it is true that the first train is going faster than the second one.
