Final answer:
The freight train's speed is calculated by dividing the distance traveled, 8/10 mile, by the time taken, 1/3 hour, which results in a speed of 2.4 miles per hour.
Step-by-step explanation:
The question pertains to calculating the speed of a freight train that travels a certain distance within a specified timeframe. To find the speed of the train in miles per hour (mph), we can use the formula Speed = Distance / Time. The question states that the train travels 8/10 mile in 1/3 hour. To determine the train's speed, we divide the distance by the time:
- Speed = (8/10) miles / (1/3) hour
- Speed = (8/10) * (3/1) = 24/10
- Speed = 2.4 miles per hour
Therefore, the freight train's speed is 2.4 miles per hour.
