Answer:
300 miles.
Step-by-step explanation:
Distance = Rate * Time
We know the rate, 80 miles per hour.
We know the time, 3.75 hours.
As these use the same time unit, hours, we don't need to change any values.
We can just put these values into the formula:


Answer: 300 miles.
Answer:
2/7
Step-by-step explanation:

Area=length times width
area=10.5
length=3.5
10.5=3.5 times width
divide both sides by 3.5
3=width
width=3ft
If the train travels 744 miles in 3 hours then to determine the unit rate the train is traveling per hour you have to divide the miles by the hours, in this case (744 miles)/(3 hours). The final result concludes as 248 miles per hour.
