Final answer:
To find Rachel's marathon finish time in minutes, multiply her finish time in hours (3.8) by the number of minutes in an hour (60), getting a result of 228 minutes.
Explanation:
To convert Rachel's marathon finish time from hours to minutes, we need to multiply the number of hours by the number of minutes in one hour. Since there are 60 minutes in one hour, we calculate the finish time in minutes by multiplying 3.8 hours by 60 minutes.
Finish time in minutes: 3.8 hours × 60 minutes/hour = 228 minutes.
Therefore, Rachel finished the marathon in 228 minutes.
