Answer
# Explanation:
## Step1: Calculate rate per minute
The rate of knee - lifts per minute is found by dividing the number of knee - lifts by the time. So the rate $r=\frac{50}{2}=25$ knee - lifts per minute.
## Step2: Calculate number of knee - lifts in 3 minutes
Multiply the rate per minute by the new time. So the number of knee - lifts $n = 25\times3=75$.
