Final answer:

To calculate how long it would take a rocket to travel from Earth to Mercury, divide the distance (9.21×107 km) by the rocket's speed (3.93×104 km/h). The result is 23434.35397 hours, which rounds to 2336 hours.

Step-by-step explanation:

The question is asking how long it would take for a rocket traveling at a speed of 3.93×104 kilometers per hour to traverse the distance from Earth to Mercury, which is 9.21×107 kilometers.

To solve this, we divide the total distance by the speed of the rocket:

Time = Distance / Speed

Time = (9.21×107 km) / (3.93×104 km/h)

Time = (9.21×107) / (3.93×104) hours

Time = 23434.35397 hours

When rounded to the nearest whole number, the time becomes 2336 hours, which is the answer we are looking for.

Hence, the correct answer is: C) 2336 hours.
