Convert Rachel's marathon finish time of 3.8 hours to minutes.
Solution: $3.8 \text{ hours} \times 60 \text{ minutes/hour} = 228 \text{ minutes}$

STEP 1

Assumptions
1. Rachel finished a marathon in 3.8 hours.
2. There are 60 minutes in 1 hour.

STEP 2

To find Rachel's finish time in minutes, we need to convert hours into minutes. We can do this by multiplying the number of hours by the number of minutes in one hour.
$Finish\, time\, in\, minutes = Finish\, time\, in\, hours \times Number\, of\, minutes\, in\, one\, hour$

STEP 3

Now, plug in the given values for the finish time in hours and the number of minutes in one hour to calculate the finish time in minutes.
$Finish\, time\, in\, minutes = 3.8\, hours \times 60\, minutes\, per\, hour$

STEP 4

Calculate the finish time in minutes.
$Finish\, time\, in\, minutes = 3.8 \times 60$

STEP 5

Perform the multiplication to find the finish time in minutes.
$Finish\, time\, in\, minutes = 228$
Rachel's finish time in minutes is 228.
