Determine Editing Rate: Determine the rate at which Mabel edits videos. Mabel spends 4 hours to edit a 3-minute video. To find her editing rate, we divide the total time spent by the length of the video. Rate = Time Spent / Video Length Rate = 4 hours / 3 minutes To keep the units consistent, we should convert the video length from minutes to hours since the time spent is in hours. There are 60 minutes in an hour, so 3 minutes is 3/60 hours. Rate = 4 hours / (3/60 hours)Convert Video Length: Calculate Mabel's editing rate. Now we perform the division to find the rate. Rate = 4 hours / (3/60 hours) Rate = 4 hours / 0.05 hours Rate = 80 hours per hour (which means Mabel spends 80 hours editing for every hour of video)

Determine Editing Rate: Determine the rate at which Mabel edits videos. $\newline$ Mabel spends $4$ hours to edit a $3$ -minute video. To find her editing rate, we divide the total time spent by the length of the video. $\newline$ Rate $= \frac{\text{Time Spent}}{\text{Video Length}}$ $\newline$ Rate $= \frac{4 \text{ hours}}{3 \text{ minutes}}$ $\newline$ To keep the units consistent, we should convert the video length from minutes to hours since the time spent is in hours. $\newline$ There are $60$ minutes in an hour, so $3$ minutes is $\frac{3}{60}$ hours. $\newline$ Rate $= \frac{4 \text{ hours}}{(\frac{3}{60} \text{ hours})}$
Convert Video Length: Calculate Mabel's editing rate. $\newline$ Now we perform the division to find the rate. $\newline$ Rate = $\frac{4 \text{ hours}}{(\frac{3}{60} \text{ hours})}$ $\newline$ Rate = $\frac{4 \text{ hours}}{0.05 \text{ hours}}$ $\newline$ Rate = $80 \text{ hours per hour}$ (which means Mabel spends $80$ hours editing for every hour of video)
