To find the speed of the A train in miles per hour, you can use the formula:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
In this case, the A train travels 300 miles in 8 hours. So we can plug in the values:
\[ \text{Speed} = \frac{300 \text{ miles}}{8 \text{ hours}} = 37.5 \text{ miles per hour} \]
Now, we need to fill in the question marks in the format provided:
?/?=?/1 hour
We can relate this to the answer choices:
- We can assign "b. 300 miles" as the distance.
- We can assign "a. 8 hours" as the time.
- The speed we just calculated, which is "37.5 miles," would be represented by "d. x miles."
- The "c. x hours" part would correspond to the time taken, which is not directly filled in since we already used "8 hours."
So, putting it all together:
\[ \frac{300 \text{ miles}}{8 \text{ hours}} = \frac{37.5 \text{ miles}}{1 \text{ hour}} \]
Fill in the blanks with the respective choices:
b. 300 miles / a. 8 hours = d. 37.5 miles / 1 hour
Thus, the filled-in format is:
300 miles / 8 hours = 37.5 miles / 1 hour
