Final answer:
To calculate the driving time for a 1700-mile trip at 51 miles per hour, divide the distance by the speed giving approximately 33.3 hours.
Step-by-step explanation:
To calculate the driving time for a 1700-mile trip at a speed of 51 miles per hour, you can use the formula:
Time = Distance / Speed
Substituting the given values:
Time = 1700 miles / 51 miles per hour ≈ 33.333 hours
Therefore, rounding to one decimal point, the driving time for a 1700-mile trip at a speed of 51 miles per hour would be approximately 33.3 hours (Choice b).
