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?


To find out how many knee lifts Darnell will do in 3 minutes, we first need to determine the rate at which he performs knee lifts per minute.

From the problem, we know that Darnell did:
- 50 knee lifts in 2 minutes.

Thus, the rate of knee lifts per minute is:
\[
\text{Rate per minute} = \frac{50}{2} = 25 \text{ knee lifts per minute}.
\]

Now, since Darnell will be doing knee lifts for 3 minutes at the same rate, we can calculate the total number of knee lifts as:
\[
\text{Total knee lifts} = 25 \times 3 = 75 \text{ knee lifts}.
\]

Therefore, Darnell will do **75 knee lifts** today.

Would you like any further details or clarifications?

Here are five related questions to consider:
1. How many knee lifts would Darnell do in 5 minutes at the same rate?
2. If Darnell increases his rate to 30 knee lifts per minute, how many will he do in 3 minutes?
3. How long would it take Darnell to do 100 knee lifts at his current rate?
4. If another player does 20 knee lifts per minute, how many more knee lifts does Darnell do in 3 minutes?
5. How many knee lifts would Darnell do if he only performed for 1 minute?

**Tip**: When solving rate problems, dividing the total by time gives the rate per unit, and multiplying this rate by a new time gives the total for that time.
