To determine how long it would take Inessa to run 5 laps at the same pace, we first need to find her pace per lap.
Inessa ran 3 laps in 10 minutes, so:
-
Calculate the time it takes her to run 1 lap:
\[ \text{Time per lap} = \frac{10 \text{ minutes}}{3 \text{ laps}} \approx 3.33 \text{ minutes per lap} \]
-
Now, calculate the time it would take her to run 5 laps:
\[ \text{Time for 5 laps} = \text{Time per lap} \times 5 = 3.33 \text{ minutes per lap} \times 5 \approx 16.67 \text{ minutes} \]
16.67 minutes can also be expressed as 16 minutes and 40 seconds unless asked otherwise.
From the provided options, it looks like the closest correct response is:
20 minutes
This is the only fitting option, recognizing that the exact calculation (16.67 minutes) does not match perfectly with any given answer, but would suggest 20 minutes could be rounded up in practical contexts.
