Racing Model Cars: Salim and Jia

Salim and Jia are racing model cars traveling at constant speeds. How far ahead of Jia's car is Salim's car after 3 seconds?

A) The same distance

B) Twice the distance

C) Three times the distance

D) Four times the distance

Final answer:

Without knowing the speeds of Salim's and Jia's model cars, we cannot determine the relative distance by which Salim's car is ahead of Jia's car after 3 seconds.

Explanation:

The question pertains to the relative distances covered by two model cars, Salim's and Jia's, traveling at constant speeds over a period of 3 seconds. To determine how far ahead Salim's car is as compared to Jia's car after 3 seconds, we would need to know the speed of both model cars, which is not provided in the question. Because key information is missing (the speeds of Salim's and Jia's cars), it's impossible to accurately calculate the distances without making assumptions. Therefore, we cannot determine whether the distance is the same, twice, three times, or four times ahead.
