2) During one year,Mark drove his car a total distance of 2times 10^5 miles.He drove for 4.5times 10^4 minutes.What was his average speed in miles/min (distancediv time) ? Write your answer in standard notation.

To find Mark's average speed in miles per minute, we need to divide the total distance he drove by the total time he drove.

Given information:
- Total distance driven: $$2 \times 10^5$$ miles
- Total time driven: $$4.5 \times 10^4$$ minutes

Step 1: Divide the total distance by the total time to find the average speed.
Average speed = Total distance / Total time
Average speed = $$(2 \times 10^5$$ miles) / $$(4.5 \times 10^4$$ minutes)
Average speed = $$4.44 \times 10^0$$ miles/minute

Therefore, Mark's average speed was 4.44 miles per minute.
