We can use the distance formula, which is:

distance = rate x time

We know that distance is 1500 km and rate (or speed) is 100 km/h. Let's solve for time:

1500 = 100t

Divide both sides by 100:

t = 15

Therefore, it would take 15 hours to drive 1500 kilometers if the average rate of speed is 100 kilometers per hour. So, the answer is D. Using the distance formula:

distance = rate x time

We are given that the distance is 1500 kilometers and the rate is 100 kilometers per hour. We can plug these values into the formula and solve for the time:

1500 = 100t

t = 1500/100

t = 15

Therefore, it would take 15 hours to drive 1500 kilometers at an average rate of 100 kilometers per hour. The answer is D).
