Final answer:
The speeds of the vehicles cannot be determined without additional information.
Step-by-step explanation:
To determine the speed of vehicle 1 before and at the impact of vehicle 2, we need more information. The provided information only gives us the distances skidded by both vehicles before and after the impact. We would need the time it took for vehicle 1 to skid and the time it took for vehicle 2 to spin off the road to calculate their speeds. Without this additional information, we cannot determine the speeds of the vehicles. Therefore, the correct answer is option A: Not enough information provided.
