The correct answer is D. ( t = frac{15}{20} ).
To find the time ( t ) needed for the ride, you can use the formula:
[ t = frac{text{distance}}{text{speed}} ]
In this case, the distance is 15 miles and the speed is 20 miles per hour. So:
[ t = frac{15 text{ mi}}{20 text{ mi/h}} ]
This simplifies to ( t = frac{15}{20} ), giving you the time in hours. Remember to check the extended services page for more in-depth assistance if needed!
