Answer 1

Francesca walked with a speed of 101.2 yards per minute by walking a total distance of 708.4 yards in 7 minutes.

Step-by-step explanation:

To determine how fast Francesca walked, we need to calculate the distance she walked and then divide it by the time it took.

First, we calculate the total distance Francesca walked:

Total distance = Number of laps × Distance per lap

Total distance = 1.61 laps × 440 yards/lap

Total distance = 708.4 yards

Now we calculate the walking speed:

Walking speed = Total distance ÷ Time

Walking speed = 708.4 yards ÷ 7 minutes

Walking speed = 101.2 yards per minute

Therefore, the correct answer is:

D. 101.2 yards per minute

Answer 2

If each lap is 440 yards, Francesca walked 115 yards per minute.
