To find the average time it would take for the race car to complete 6 laps around a track of 2500 m, we can follow these steps:
1. Calculate the total distance for 6 laps:
\[
\text{Total distance} = \text{Track length} \times \text{Number of laps} = 2500 \, \text{m} \times 6 = 15000 \, \text{m}
\]
2. Using the speed of the race car, calculate the time it takes to cover this total distance. The formula to find time is:
\[
\text{Time} = \frac{\text{Distance}}{\text{Speed}} = \frac{15000 \, \text{m}}{100 \, \text{m/s}} = 150 \, \text{s}
\]
Thus, the average time it would take for the car to complete 6 laps on the track is **150 seconds**.
The correct answer is: **150 seconds**.
