Question

Ms.Wooldridge walks laps around her pool for exercise each day. She walks at a constant rate of 30 seconds per lap. It takes her 46 steps to walk one full lap. Each step is approximately 1 foot. How many minutes will she walk in one mile?

Answer 1

Answer: it will take her 58 minutes to walk one mile.

Step-by-step explanation:

She walks at a constant rate of 30 seconds per lap and it takes her 46 steps to walk one full lap. It means that she walks 46 steps in 30 seconds.

If each step is approximately 1 foot, it means that the number of feet that she walks in 30 seconds is 46 feet.

1 foot = 0.000189 miles

Therefore, 46 feet would be

46 × 0.00189 = 0.008694 miles

Therefore, if she she walks 0.008694 miles in 30 seconds,

The time it will take her to walk 1 mile would be

30/0.008694 = 3450.66 seconds

Converting to minutes, it becomes

3450.66/60 = 58 minutes
