Lena types at a rate of 10 words per minute.
How many words does she type in 5 minutes?
To find the rate in acres per day, we need to divide the total number of acres (21 acres) by the number of days (7 days).
Rate (acres per day) = Total acres / Number of days
Rate (acres per day) = 21 acres / 7 days
Now, let's do the calculation:
Rate (acres per day) = 3 acres per day
So, the rate at which the group of workers can plant is 3 acres per day.
