To find the time it takes to travel a distance using the formula d = r * t (where d is distance, r is rate or speed, and t is time), we can rearrange the formula to solve for time (t):
\[ t = \frac{d}{r} \]
In this case:
- Distance (d) = 375 miles
- Speed (r) = 230 mph
Now, plug in the values:
\[ t = \frac{375 \text{ miles}}{230 \text{ mph}} \]
Calculating:
\[ t \approx 1.6304 \text{ hours} \]
This rounds to approximately 1.6 hours.
So the correct answer is **c. 1.6 hours**.
\[ t = \frac{d}{r} \]
In this case:
- Distance (d) = 375 miles
- Speed (r) = 230 mph
Now, plug in the values:
\[ t = \frac{375 \text{ miles}}{230 \text{ mph}} \]
Calculating:
\[ t \approx 1.6304 \text{ hours} \]
This rounds to approximately 1.6 hours.
So the correct answer is **c. 1.6 hours**.
