Question

lily took 57 seconds to walk from schoolroom to library. if the distance between the classroom and library was 38m, at what average speed did lily walk in m/min?

Answer 1

Lily walked 38 meters in 57 seconds, which is equal to 0.95 minutes. Her average speed was 38 m / 0.95 min, which is approximately 40 meters per minute.

Step-by-step explanation:

The student's question is about calculating the average speed at which Lily walked from the schoolroom to the library. To find her average speed, we will use the formula:

speed = distance / time

Lily walked a distance of 38 meters in 57 seconds. Since we need the speed in meters per minute (m/min), we first convert 57 seconds into minutes by dividing by 60. So, 57 seconds is equal to 57/60 minutes.

Now, we can calculate her average speed.

Average Speed = 38 m / (57/60) min
= 38 m / 0.95 min
= 40 m/min (rounded to the nearest whole number)

Lily walked at an average speed of 40 meters per minute from the schoolroom to the library.
