Darnell's baseball team always does warm-ups before a game. Before last week's game, Darnell did 50 knee lifts in 2 minutes. Today, he will do knee lifts for 3 minutes.
If he does them at the same rate, how many knee lifts will Darnell do today?
knee lifts
If Darnell did 50 knee lifts in 2 minutes, then he did 50/2 = <<50/2=25>>25 knee lifts per minute.
If he does them at the same rate, he will do 25 knee lifts in 1 minute.
Since he will do knee lifts for 3 minutes today, Darnell will do 25*3 = <<25*3=75>>75 knee lifts today. Answer: \boxed{75}.
