Question

Lin runs 2 laps around a track in 8 minutes.

Answer 1

Answer:

Part a: 4 minutes

Part b: $\frac{1}{4}$ lap

Part c: 84 minutes or 1 hr and 24 minutes

Step-by-step explanation:

Part a:

Ok so you got part a right, it's 4 minutes.

Part b:

you would do $\frac{2laps}{8min.}$ that will give you $\frac{1}{4}$.

So it's a quarter of a lap per minute.

Part c:

For this one we know that it takes her 4 minutes just to complete one lap, and if they're doing 21 laps that means we'll multiply 21 and 4. That gives us 84 minutes, or 1 hr and 24 min.
