Question

For exercise, Francesca walks laps around a track. She walked 1.68 laps around the track in 7 minutes. If each lap is 440 yards, how fast did Francesca walk?

A) 220 yards per minute
B) 62.9 yards per minute
C) 672 yards per minute
D) 105.6 yards per minute

Answer 1

Francesca walked at a speed of 105.6 yards per minute. Therefore, the correct answer is D) 105.6 yards per minute.

So, 739.2 yards / 7 minutes = 105.6 yards per minute.

Step-by-step explanation:

To find out how fast Francesca walked, we need to divide the total distance she walked by the total time it took her.

First, we need to convert the number of laps she walked to yards by multiplying it by the length of each lap, which is 440 yards. So, 1.68 laps * 440 yards/lap = 739.2 yards.

Next, we divide the total distance, 739.2 yards, by the total time, 7 minutes, to find the speed.

So, 739.2 yards / 7 minutes = 105.6 yards per minute.

Therefore, the correct answer is D) 105.6 yards per minute.
